Javascript bracelet builder (updated)

I have an e-shop that is currently using Magento eCommerce platform. I need for a "bracelet builder tool" that works exactly like [login to view URL] to be integrated into the Magento platform Initial page is to choose bracelet and it attributes (material, size and etc.) from the braselets database. Next page is to choose items for the barcelet. The right window is the list of "categories", would be pulled from the existing database and would update whenever more categories are added. The section in the middle would pull the products from each category in the database when a category is clicked on. To add item to the bracelet, user should "drag-n-drop" chosen item to the desired bracelet area at the upper part of the window. The click on an item to view the description would work the same way... the product picture, the product ID, and the product name would appear in the lower right corner. All info would be pulled from the database. The "Finish" button at the bottom right corner would actually become an "add to cart" button and by clicking this all of the products that are on the bracelet, as well as the bracelet itself, would be added to the shopping cart. All of the images and content that would populate the javascript bracelet builder would be pulled from the existing Magento database so that it will update whenever more products are added automatically. All windows settings, listing settings, should be set by using standard Magento and template options. All additional details by request.
