CGRectMake(0.0f, th, w, h - th) style:UITableViewStylePlain] retain];
mTableView.autoresizingMask = UIViewAutoresizingFlexibleWidth |
UIViewAutoresizingFlexibleHeight;
mTableView.dataSource = self;
mTableView.delegate = self;
[mTableView setRowHeight:55];
[self.view addSubview:mTableView];
data = [[[NSMutableArray alloc] init] retain];

You should have a view controller that contains your table view (it could even be a subclass of UITableViewController). I don't believe that UINavigationController is mean't to be subclassed as you have. If you want a navigation controller you should create an instance of CustomTableViewController, containing your tableview, and then use the initWithRootViewController: method of UINavigationController:
CustomTableViewController * ctvc = [[CustomTableViewController alloc] init];
UINavigationController * navigationController = [[UINavigationController alloc] initWithRootViewController:ctvc];
[ctvc release];
// Superview is where you want this added
// probably your window in app did finish launching
[superview addSubview:navigationController.view];
[navigationController release];
