Howdy Joshua, I read your question and was thinking about it when the announcement that Google is open sourcing App Inventor came out https://groups.google.com/d/topic/app-inventor-announcements/KOElwBV3sVs/discussion and got tied up :-)
Google Apps Script (GAS) uses JavaScript running on the server, Docs or Sites or ... I think Robert's suggestion is what I would do. I did a simple test of the Licensing API for Google Chrome Web Store that did the authentication in Python (and the Java one for fun) and then the app did various HTML5 things, not even GAS. It was not complex, but may give you an idea. and there are various choices to get at data. I am currently planning on testing GAS with some of the data in Fusion Tables. I do not know if that makes the authentication any easier but it is yet another choice rather than migrate the data. and JavaScript looks pretty much like Java or Python to me. Go with which you are more comfortable with if that is what you do. and let us know what you end up doing.
