Making it a MultiThread!

Thanks for getting back to me, so i assume it is OK to have a very very long file? The sample code i posted here is basically the barebones of the main app. 
so, combining the GUI-file(gui.py)  with main code is acceptable? Separating them into modules was initially the attempt to keep things in order.
