The canonical example of overlaying Cocoa controls on OpenGL content is:
Basically, you need to use not only NSViews but CALayers also. VTK includes an NSView subclass, but does not include any CALayer subclass. *It's something I'm hoping to do one day when I miraculously have free time.) But it's not too hard to make your own CAOpenGLLayer subclass and tell the vtkrenderwindow to draw into it. I know nothing about Qt, so getting that into the mix will be another wrinkle I'm sure!
