Little window script

hi,

I'm sorry but I'm know nothing about mel scripting, but i like to have a little popup window that it can dysplay a return value from that :

// end button: //
$totalTime = timerX -startTime $startTime* 25;
print ("Total Time: "+$totalTime+"n");

it's come from http://www.highend3d.com/boards/showflat.php?Cat=1,2&Board=mayaanimation&Number=192633&page=0&view=collapsed&sb=5&o=&fpart=

If someone can help me, thank

Have fun
