I don't know how config.py is structured. But my inclination would be create a 
fileConfig class in it with an __init__ that takes as its attributes the pwd 
and projname. You would create an instance of this class in newFile() and 
pass it the attributes from wd.GetPath() and  ted.GetValue(). This instance 
would then be passed to OnNewMod() and the attributes would carry over. This 
solves the problem of what to do if more than person writes to config.py at 
the same time. A class approach would give each call to the class a custom 
set of attributes. This is not tested and runs the risk of different parts of 
the app calling newFile() and getting the same class instance when in fact 
they may need different instances.
