Well, it's fine to ask Windows-specific questions on the general GTK+
lists, too.

Yeah, sounds exactly as it should be. Except that I don't know about
the "signalling" part, I am not sure how that is actually implemented
(I am not a C++ person), and whether it works with the GLib mainloop.
I would just use g_idle_add() instead.

Have you built the app as a "gui" executable? It might be printing
something to stdout or stderr, but in a "gui" executable that goes
nowhere. Build it as a "console" executable instead.
