Well, what follows is not a direct display from gawk, but close to it.

Please find attached a little tksimple.awk library that interfaces a 
gawk script with a Tcl/Tk interpreter by means of a two-way pipe (the 
gawk |& operator). And a tktest.awk example is also attached. To test, 
just run:

     gawk -f tktest.awk

This requires a gawk version that supports two-way pipes (the |& 
operator), and a Tcl/Tk interpreter (tclsh/wish commands).

In my Ubuntu 64 bits box the screen is updated almost instantly at every 
step. Maybe it also fill your expectations.

HTH. Regards.
