Another common solution is to make the main .exe a GUI, then have a
separate tiny non-GUI wrapper program that runs the main GUI, captures
the output, and connects to stdin/stdout.

In my project I have nip2.exe, my main GUI app, then nip2-cli.exe, a
command-line program that runs nip2.exe and redirects. Here's the
source:

  http://vips.svn.sourceforge.net/viewvc/vips/nip2/trunk/src/nip2-cli.c?view=markup

It could probably use one of the g_spawn_*() functions and save some
space, but it's adapted from another non-glib project.
