  Look at "bigjob" in the set of demo packages.  It's specifically a
simple example of bolting a GUI onto an existing, non-GUI, "big job"
program.  In essence, when the program wants to write to the screen,
instead of using Ada.Text_IO, it puts the info into a status record and
calls for a screen redraw.  The redraw shows the new (or what's changed)
info from the status record.  Asynchronous user window menu selections
similarly put information in a command record, and the main program, at
appropriate times, looks there to see if it needs to take some action.
The "Bigjob" demo doesn't show user input requests from the main program
(ie, Ada.Text_IO.Get) - that's done with dialog boxes.  See the other
demos or docs for those.
  You mention your Ada program runs on DOS - which compiler did it use?
