Django based Facebook app BACKEND only hosting:heroku

I need to do a PROTOTYPE of an app that allows students to solve tests. It has to - be in django - be integrated with Facebook ->login via facebook only - I want to temporarly host it on heroku [free SSL hosting for facebook apps] so it has to installed there [login to view URL] - the app shows students the list of short tests - they solve the tests and can challenge other users (eg user 2). - User2 answers the challenge by clicking on it and solving a test (random one) Results are compared and winner gets his score doubled. -Users keep track of challenges and obtain notifications via the app - so database is required. -Also I need django admin to be enabled to allow to edit tests and questions. The wire-framing of the app is available here - sorry it is currently in an obscure language known as Polish. [login to view URL] No frontend programming (unless you can do bootstrap) just printing data to empty html page like this {{some_data}}
