One way to do this that I haven't seen posted here yet is to assume that
GTK is available and use gtk_init_check() to initialize
it. gtk_init_check() behaves just like gtk_init() except that it does not
terminate the program if the GUI can't be initialized; instead it returns
a false gboolean value. This solution is probably more portable than
using the DISPLAY variable since it isn't X specific. It should work on
Windows, GTK running on a framebuffer, or whatever.
