Let's say in my AppController a new Non-modal window is getting

Of course I will have to release the controller at some stage.
Since you've mentioned that this is a shared non-modal panel of some
sort, you might want to consider making it a singleton controller. (I
generally don't advocate "enforced" singletons in Cocoa -- overriding -
retain, -release and so on -- just always going through a
sharedWhatever class method.)
Then your method above just becomes something like this:
- (IBAction)orderFrontSomethingPanel:(id)sender { // renamed for Cocoa
conventions
[[SomethingPanelController sharedSomethingPanelController]
showWindow:self];
}
Since the shared panel is a global, you don't have to worry about
releasing it or whether it's considered a leak (it should be
recognized as a global and not considered one).
If the panel needs to be "reset" between uses, you can make the window
controller a delegate of the window and reset its state when the
window will close. This way, you can work with the window controller
as you would any other in Cocoa, and it will handle the special
behavior it needs itself.
