Where to start for this mini game

it’s for educational purposes

i.e. kids playing it will try to differentiate between healty food and junk food…

on screen there will be a basket for HEALTHY FOOD
and a trash can for JUNK FOOD

the child playing the game will drag the food into basket or trash can, depending upon the nature of the food i.e. healthy and not-so healthy food items…

I am fimilar with basic action scripting, but i need a starting point for this particular game.

any ideas, guidelines or links to tutorials will be highly appreciated
