How to make a more "advanced" shutdown shortcut?

Well i was just wondering if there was a way to make the shutdown -s -t 30 -c "VIRUS DETECTED!!" shutdown shortcut a bit more advancedBasically all i want to do is tie a game to it. Just a small flash game cause my plan is to give it to a friend then they play the game and ill set the timer to 10 mins or something and then ten minutes later it comes up, they'll freak out, they wont blame me ^.^So is there anyway to do that?
