Write these properties in AppDelegate.h file

@property (strong, nonatomic) YourFirstViewController *yourFirstController;
@property (nonatomic, retain) UINavigationController *navigationControl;

Write this code in AppDelegate.m file

  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {

        self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
        self.yourFirstViewController = [[YourFirstViewController alloc] initWithNibName:@"YourFirstViewController" bundle:nil]];
        navigationController = [[UINavigationController alloc] initWithRootViewController:self.yourFirstViewController];
        [self.window addSubview:[navigationController view]];
        [self.window makeKeyAndVisible];
        return YES;
    }

I think it will be helpful to you.

Being your app view based, you can't push the controller, the simplest thing to do is:

PlanPage *yourViewController = [[PlanPage alloc] initWithNibName:@"PlanPage" bundle:[NSBundle mainBundle]];
[self.view addSubView:yourViewController.view];
[yourViewController release];

If you want to animate it, I'm afraid you have either to implement the animation by yourself, or to add a navigation controller to do the job for you
