Actually, XTerm does support the current selection mechanism in addition to
cut buffers - otherwise you wouldn't be able to paste from GTK+
in xterm.

It should work, assuming that you send the event ot the right subwindow.
(see gtk_text_button_press.)

If you want to do it external to the application, then this is about
the only way you are going to be able to do it, unless the app has
an application-specific control interface. 

I'm still quite unable to imagine your application, so making other
suggestions is beyond me at this point.
