Is there any reason why you can't work with GTK 2.0's XSettings client? 
(the GtkSettings object).  You can register new XSettings properties you 
are interested in with gtk_settings_install_property() (if it hasn't 
already been registered by gtk+), then use the standard g_object_get() 
API on the GtkSettings object to read values, and listen on the 
"notify::propertyname" signal to get notification when the setting changes.
