Windows PE executables have a nice feature where there's a resource
section which is by convention used for strings and also graphics like
the program's icons. This is common and natural on Windows, so if you
can load the file dynamically at runtime and set icons explicitly,
then provided your cross compiler is able to include the needed PE
section, you can build a self-contained file which is one .exe with
all the needed code and data/resources. This feature of PE files
is as old as Windows itself and will work, if that's a concern of
yours, if you can generate the desired .exe and can convince
GTK+ to load stuff at runtime manually.
