You'd probably get better answers on a GTK+ (or XLib) related mailing 
list but I think this function does what you want:

https://developer.gnome.org/gdk-pixbuf/unstable/gdk-pixbuf-X-Drawables-to-Pixbufs.html#gdk-pixbuf-xlib-get-from-drawable

And then create the GtkImage from the GdkPixbuf. I'd probably use Cairo 
for this myself since you can just make a surface from the Pixmap and 
draw it straight onto whichever widget you need (ex. a GtkDrawingArea).
