See:

    http://www.dmitry-kazakov.de/ada/gtkada_contributions.htm#10

with callbacks for each input/output lines:

    http://www.dmitry-kazakov.de/ada/gtkada_contributions.htm#10.1

with text buffers to standard input/outputs:

    http://www.dmitry-kazakov.de/ada/gtkada_contributions.htm#10.1

The sample code are Test_Gtk_Asynchronous_Spawn and Test_Gtk_Spawn.

P.S. It is a complicated issue you better avoid if you can.
