Just a note that condor_tail can be used to view any file in the job's 
execute directory, not just stdout/err.

Szabolc, an additional idea to consider for your GUI is be aware that 
stdout/err can be real-time streamed from the execute machine back to 
anywhere on the submit machine by settings "stream_output" and 
"stream_error" in the job submit file; see the man page for 
condor_submit for details.

regards,
Todd
