You might put your libraries in your development directory :

/path/devel
/path/devel/mylibraries
/path/devel/mylibraries/graphiclibraries
/path/devel/mylibraries/databaselibraries
/path/devel/myapplications/mynewapplication

Then inside /path/devel/myapplications/mynewapplication/myprogram.py
when you want to access a module you just write :

import mylibraries.mygeneralmodule
from mylibraries.mygeneralmodule import x

import mylibraries.graphiclibraries.mygraphiclibrary
from mylibraries.graphiclibraries.mygraphiclibrary import x

import mylibraries.databaselibraries.mygraphiclibrary
from mylibraries.databaselibraries.mygraphiclibrary import x

Of course /path/devel must be in your path, but as long as the rest of
the structure remains unchanged you may place your stuff anywhere.
