Normally people embed a Motif widget in GTK, not the other way
around. Mozilla can embed legacy plugins from Netscape 4.x, which
embeds Motif in GTK. So this is definitely possible in that direction.

I don't know of anyone who's done it the other way, putting GTK in
Motif. The general line of attack I would look at is putting the GTK
widget in a GtkPlug, then trying to emulate GtkSocket on the Motif
side, possibly even putting the GTK widget in a separate process from
the Motif app. If you use the widget systems in the same process, you
would want to merge the main loops, presumably you can copy XtBin or
Mozilla there.
