You haven't heard about Red (http://www.red-lang.org), have you? With some Kb you can ship GUI executables for Windows, Android, OSX and Linux. (OSX and Linux soon).
Try it and report back the amount of Kb (not Mb) used.

EDIT: The version on their download page doesn't make GUI's for OSX yet, but there seem to be other versions that do.
