Well, I don't have any experience with Maya at all, but what you need 
seems pretty straight forward. I would subclass QDialog, show (or 
exec_) the non modal dialog, and collect the data when closed.

The gory details depend on how Maya runs such extension code (eg. how 
QApplication and the event loop is handled).
