  You don't need gnome for modal windows. GTK already does it with
gtk_window_set_modal.  What gnome has is a function that you call on a
dialog and never returns until a button has been pressed or the dialog
closed, which is a useful thing.

  Yes, I'm sure you could do this with GTK as well with just a bit of
work. And you don't even need semaphores, I think.
