Found this great website/howto on creating self contained python applications that run like any other applications in OS X.
Then follow the directions here:
http://svn.pythonmac.org/py2app/py2a...doc/index.html
The key to this is when creating your own standalone python application is to specify that you want to use python2.5 in the creation of your application.
Feel free to PM me if you need any help getting this to work for you.
