I'm hoping to add functionally to the C++ app.  Therefore, I intended 
that a menu selection from the C++ would call my python code (I was able 
to do that with PythonQt).  Then run my scripts as if they were in the 
normal PyQt loop - but now running in the C++ app loop.

So I see dialogs opening with all the normal PyQt Qcontrols include data 
views etc..  I also want all future code to be written in python and 
added to the C++ app.  In the future completely replacing many of the 
parts currently written in C++.  Today we are writing stand alone python 
apps outside of the C++ app to get special needs completed that should 
be in the app.  The reason we are doing this is to get it to the user as 
fast as possible.  It was intended that these python scripts be 
rewritten in C++ at one time - but it takes time to get that done and 
python is so much more productive.
