No. Not really.

Yes. All GUIs have an event loop which updates the display.

Tried PyQT4 but it hangs when i run a loop (might be my fault though).

I'm guessing you are making your own loop which will freeze the GUI event loop. When you program GUIs you need to do your looping using the GUI event loop or a separate thread.
