How can I create a custom project layout based on another eclipse plugin? - eclipse

Question

My ultimate goal is to create an eclipse plugin that sets up a PDT project, but with some added builders (and custom build scripts) as well as a specific folder layout (and different folders should be treated as source and some as regular folders).
I've looked at / followed eclipse plugin development tutorials, and ok. I get the gist of creating a wizard that creates a file, but I'm having trouble trying to figure out how to create a project, and more importantly, make that project associated with the PDT (PHP Development Tools) feature.
Answer:
I did stumble upon a solution myself before the answer was given, but it's quite similar.
First, WizardNewProjectCreationPage was used as the first page of my wizard.
Second, on performFinish() I ran the following code:
IProgressMonitor m = new NullProgressMonitor();
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IProject project = root.getProject(_pageOne.getProjectName());
if (!project.exists())
{
IProjectDescription desc = project.getWorkspace().newProjectDescription(project.getName());
URI projectLocation = _pageOne.getLocationURI();
// desc.setLocationURI(projectLocation);
String[] natures = desc.getNatureIds();
String[] newNatures = new String[natures.length + 1];
System.arraycopy(natures, 0, newNatures, 0, natures.length);
newNatures[natures.length] = PHPNature.ID;
desc.setNatureIds(newNatures);
project.create(desc, m);
project.open(m);
}

how to create a project
Take a look at BasicNewProjectResourceWizard.createNewProject() method.
make that project associated with the PDT (PHP Development Tools) feature
You need to add "org.eclipse.php.core.PHPNature" to the project (that's what Add PHP Support... action does). Use IProjectDescription.setNatureIds().
