I few years ago I helped my wife create a tutorial in the Renpy visual 
storytelling engine.  It is free and open source.
It is written in Python, while users write scripts in both Python and a 
custom scripting language.

When we were done, we pressed a button and it generated self-contained 
zip files for Windows, Linux, and Mac.  This can  be done from any of 
the three platforms.  After we tested all three files, she created a web 
page with links to the three files for download.  There have been no 
complaints so far. Perhaps the file generators could be adapted to 
packaging a project directory into a self-contained app.
