Interactive Platformer Help

Ok, I am trying to make a side scroller that sets up a push-#-do number attack kind of thing. With 4 slots. you are supposed to click on one of the boxes on the top of the screen and filter through your skills and once you have the one you want you click it again and every time you push the assigned # to that box you activate the skill. Do you have any ideas how I would go about the skill and box system? If you have played Guild Wars you should know wat i'm trying to do. Except I want to filter through the skills when you click on them. And activate the skill when you push the button.
