I've never used QT but other graphical toolkits I have used all start their own "main loop" which is a loop that cycles round receiving, queuing and dispatching "events". You probably need to call the QCoreApplication's quit method to break out of this e.g. app.exit() or something similar, have a look at some complete PyQt4 examples or google for PyQt4 mainloop.
