I beg your pardon for possibly stupid comment---I haven't practice GUI 
programming for a long time, especially in Python. However I mostly 
prefer declarative approach for the problems like that. Therefore, 
wouldn't it be interesting to describe the structure with class and 
metaclass mechanism, like:

class MainFrame(FrameDescription):

   class b1(ButtonDescription):
     size = (40, 40)
     text = "b1"

etc.

with the best regards,
anton.
