Sounds like you need to use threads.  Read about the 'threading' module.

The idea is that you would run your loop in a separate thread from the GUI
thread.  This has the additional benefit of keeping your GUI running while the
loop is running.  When you pause, create a lock which gets released when the
desired event occurs in the GUI thread..
