from the same app or from a child app?


from a child app is easy -- use shell redirection and an io watch.  
there's an example (without the redirection for stderr) in the faq:
http://gtk2-perl.sourceforge.net/faq/#46

you'd just do

   open IN, "child_program 2>&1 1>/dev/null";

instead, to send stdout to /dev/null and capture stderr.  see the bash 
manpage (or whatever shell you're using) for more info.


from the same app can be a bit tricker.  if you use Glib::Log's 
facilities for all your messages, you can use an arbitrary logging 
function to send the text wherever you want.
