Can you start the conversion from a Linux executable?

No, I can’t start the conversion from a Linux executable.
.gw files are based entirely on HTML5 technologies (like JavaScript), so they only work with web-based game builds. Native Linux executables use compiled machine code, which isn’t compatible with that format.
If you have an HTML5 version of your game, though, I can convert that without any problem.
