gtk for Windows is distributed as a dll installer, e.g. the WinGIMP
download page. GIMP on the Mac runs under X11, but in practice you
double click the gimp icon and you get the gimp program. It isn't really
a hurdle.

quick prototyping:

all modules are can be run with "--interface-description" to give XML of
all the options etc.  Loop through all the module names and capture all
the module interface commands to a file, and go from there.

The PNG driver can create PPM output which you can use to fill windows.
