Create a Simple Product Builder for Magento Website

Hi, we would like a simple product builder on our magento website that looks and works exactly the same as this website\'s product builder: [login to view URL] Instead of beds like the brosa website shows, we are going to do all different types of products like chairs, tables, sofa\'s etc with different textures, colours and style options instead. Each product will have photo renders that we will provide. We need the ability to add more options like furniture, colours and textures so you will need to show me where in the code I can do this (I will know how to do this in the source code)
