Setting up a cart with 4 products. Really one product, just with 4 flavors of the one. I've tried different variations using the attributes, options and values and can't seam to get what I want to appear.

Ie: Selling T-shirts with options of red, blue, yellow, orange. Customer needs to be able to choose any variety of the 4 options and enter a quantity that he wants for each. Example, customer wants 2 red, 1 blue and 5 yellow, but no orange. So a total of 8 t-shirts. The color options and quantity choice need to appear on same page with and add to cart button and a minimum order requirement.

Can this be done within in the existing admin or does this need to be custom programmed.
