Hi walterbyrd, I had also gone through this search earlier, but unfortunately the app generators generate a lot of code, and more imp is that inspite of this, they are not very close to what you really need. I had been evaluating these from time to time. Appgini is good but mostly from an academic view point, you can better learn from its mechanism.
Secondly, the kind of app you have in mind, is better hand coded. I recently came accross a similar project, which was eventually done by handcoding. -- http://mail.python.org/mailman/listinfo/python-list
