You can use popen(), but that only works if your backend app writes to
its standard output channel, instead of directly to the screen. And
you'll only get the output after the backend program has
terminated. DOS not being able to run several tasks (like your
frontend and backend applications), that's as far as you can possibly
get.

If your backend writes directly screen, there's no way to capture its
output, short of reinventing half of Windows' 'Virtual DOS Machine'
concept, I think.
