Not really easily. (On most OS'es, it's a flat out no - on Solaris,
with Xsun, the X server knows the pid for each client in order to do the
IA process priority manipulations, so you can dig it out with debugger
magic, but that's not something you'ld want to include in a script or
program (though I have).)
The best way to do this would be get the applications you care about
to set the _NET_WM_PID property - see the Extended WM spec at:
