"gui-freezes issues" common questions network applications in python. either network socket or stream callign blocking or timeouts set long, pipes , io stream not finished being flushed or gui's reactor not setup work network io reactor (mainloop).
typical workarounds threading network io queue.queue(), or use network package supports events, guis event driven. twisted , asyncio offer event driven io. or provided gui packages , networking packages have "reactors" (mainloops) written work other specific packages. twisted has reactors tkinter , wx example.
