Cupcake order system

I found a great example what I'm looking for here: [login to view URL] You can see: -there is a detail view for every chocolate on mouse over. -you can fill your box with chocolates with drag and drop. -you have a trash for cleaning the box and restart. I looking for something like this, but for cupcakes. What I need is a order system (I prefer a wordpress plugin) easy to use and configure, for example add new cupcakes) and in a clean and great look who fits to the website. Features: -the detail view like you see it in the example. -a box with 12 places. -the possibility to fill the box per drag and drop. -every cupcake you drag and drop fill 4 places, so there is a maximum from 3 varieties of cupcakes per box. -a trash for clean the box and restart filling. -the possibility to add a "new" badge to individual cupcakes (for example if you add a new species) -possibility to have a sound when you place a cupcake in the box. -after you click the "order button" the user get the question if he wants to fill one more box. -so it have to be possible to order more than one box. -the form for sending the order is made with google docs, you can see it here [login to view URL] it would be great to keep this form because there are many things happen in the background when you fill the form and order. But the number of boxes and the selection of the cupcake varieties must be passed to the form. All pictures and details for the cupcakes can be found on [login to view URL]
