The following code works for me. It assumes the process returns before it's done (I think all Win32 GUI programs do that, but command line ones don't - which sort are you using?).

my $PID = open my($Notepad), "|notepad.exe";
sleep 1;
print "DIE!\n";
kill 9, $PID;

Perl Monks do it more than one way.
