It's actually fairly easy.  If you have a copy of "Advanced Programming
in the Unix Environment" by W. Richard Stevens look in section 14.2,
pipes for a good intro.  He does almost exactly what you want.  If you
don't have the book, buy it. :)  I have a routine I wrote to do what
you would need (sets up the pipe, forks, connects the childs stdout to the
pipe and then runs the external program) so you can give me a yell.  Do
note that I won't respond to the list any more as this is not really on
topic for the gtk stuff.
