That's because py2app isn't part of the core distutils. You have to  
update the setup.py file (and install py2app) if you want to use  
py2app. The py2app source distribution contains a number of examples,  
including some wxPython ones. Addapting from py2exe should be fairly  
straightforward because py2app uses a simular API.

I don't know bittornado, but this is either a bug in that program or  
btdownloadgui.py is not the main entry point of the program.

BTW. Unless btdownloadgui.py startswith '#!/usr/bin/env /usr/bin/ 
pythonw' (or ... /usr/local/bin/pythonw) it won't work anyway, the  
default python interpreter cannot start full-fledged GUI apps due to  
a "feature" of OSX.
