This is serious basic stuff, u should grab a book and read through those, because, asking everything on a forum, and waiting for people to respond, will turn onto u eventually.
The thing is, do u just wonna show u something, or wonna do something with it.
U could just push a controller via a NavigationController, or just add a view, never call them windows, because an app only has one, via the appdelegate.
then use the
[self addSubview:whateveruwantview];
could be an UIImage, or another view. But the problem is, u don't know the basics. SO u need to learn those.
