No, GtkToolbar != GtkToolPalette, they are separate things.
The GtkToolPalette is what we use in Glade to show all the
widget icons for example - there is a demo of it if you run
gtk-demo you should be able to see it in action, and I'm quite
sure that it exists in one of the later versions of GTK+2
(it should really be there in 2.24).
