I am doing a project.
The first page should be the web page r 'phonegap api' html page.
when a perticular link r button is tapped , it should be taken to the native Application,purely obj C,Pure native App(with view controllers, table views etc).
Can we connect the html page with the pure native code? If yes, Then Plz tell me how?
Thanks in advance,

You could create a PhoneGap plug-in, which is a custom extension to the PhoneGap API. It includes a bit of native code that does some native-specific functionality, as well as a JavaScript interface that then exposes this functionality to you, the PhoneGap developer. By definition, a plug-in is platform-specific!
In your case, you could create a plug-in that then pushes a new View to the top of the app (overlays over the HTML page, for example).
A good place to start would be Jesse's blog post about them; note that these are specifically for iPhone:
http://blogs.nitobi.com/jesse/2010/04/01/iphonegap-plugs/
Here are some examples of existing PhoneGap plugins, how to use them, and links within to the source code to see how they were built:

i think you can do that by using the phonegap exec function

I developed GWT desktop browser application , before working on porting the Application for webkit browsers I need to have following doubts clarified:
Is it possible to map mulitple UiBinder template with the same View class?
Are the widgets consistent in look and feel for Desktop as well as webkit(mobile) browsers?
Thanking in advance.
Take a look at the mobilewebapp example which comes with the GWT SDK. There you can see, how an app can serve different views depending on the device by using deferred binding.
Using the first approach, you have different views for each device. So, you are free to choose different widgets for different platforms.
I want to share one the method that I tried, First of all instead of mapping view to viewimpl you can bind it to viewprovider, and then based on user-agent values you can return the appropriate instance to bind to.I implemented this in sample application and its working fine as of now.
On the google website there an example of a simple GWT appliatoin, following is a link:
http://code.google.com/webtoolkit/doc/1.6/tutorial/create.html
The above application has a host page:StockWatcher.html
and StockWatcher.java is the entry point.
If I wanted to add more html pages to this application, we keep one single host page and the entry point will add different panels depending on which link the user clicked on? In this case, how to know which link the user clicked on? If I create a navigation panel and each link has a request parameter, then after the user clicks on the link, How to get the request parameter?
Are there any tutorials available online on how to create a fully functional application? The one example google provides is too simple.
Thanks so much in advance
You have two options to have multiple page web application using gwt.
1) Use gwt history feature and listen for the history change. In this approach at the initial page load itself browser downloads all the javascripts(Including the widgets which are not useful in current link). Still this can be avoided by using gwt code splitting.
2) Create multiple modules. In this case you have to create multiple html pages and GWT entry points. For each major functionality create a gwt module and link that with [modulename].html file. In this approach browser downloads only particular feature's javascript. Not all the javascripts.
Based on your application requirement you can pick one of the option. IMHO I would suggesst second option.
I'm looking for a way to embed Google Docs itself--or a Google Docs-like real-time collaboration of text documents--into a web platform built with Vaadin on top of Google Web Toolkit. Currently our users won't be creating Google IDs and, ideally, we wouldn't need them to (if embedding Google Docs itself). Thanks in advance!
Could you embed the document in an iframe as shown here? (in 5.17.3 Browser Frames)
If you just need a text editor, another solution can be to embed tinymce within you GWT client:

We did it on our project and it works perfectly
Is it jQuery or some custom HTML5 framework?
It is custom javascript. I don't think they use JQuery or any framework. They are very concerned about performance so they tend to get right down to the metal. If you view the source of the page you will see that they have about 30 js files referenced. Most of their site, including touch, uses HTML5 when available for certain things. If you want to know more, you are going to have to dig through their source code.
can i design my web pages in html and css instead of java methods and use gwt only in parts of page that i need ajax? and which one is better gwt, extgwt, vaadin(it run apps in server-side.can i also use it in client-side?), etc...? do i also need to know javascript for using gwt?
thanks

Yes, you can. You can create a div on your HTML page and insert your GWT widget there.
which one is better gwt, extgwt,
vaadin(it run apps in server-side.can
i also use it in client-side?)
I don't know about vaadin but Ext-GWT is a set of ready made components to use with GWT which make your life easier especially if you want to build an web app that looks and feels like a desktop application.
do i also need to know javascript for
using gwt?
No, it can be useful sometimes but is not necessary.
