renpy at renpy.org lets one develop script for a python-based visual 
novel, simulation game (or similar visual app) and deploy on windows, 
linux, and mac.  Push a button and its creates 3 installation packages. 
  I have no idea how it does so, but it is open source.

I just checked and it now also deploys to android 2.3+ and ios6+ (in beta).
