The GLib mainloop is really nice; you get a lot of infrastructure for

As John said, glib is not like Qt; basically Qt is the equivalent of
glib and GTK+ together.  I think in Qt4 they were going to separate out
the non-GUI runtime bits.

If you use DBusServer (which isn't wrapped in GLib yet), all you need to
do is call dbus_server_setup_with_g_main.

All this stuff is handled by DBusServer.
