Simple shopping cart

First off, sorry if this has been asked a thousand times before. I thought it would have but i cant find anything.

I have been asked to make an online shop for my old boss. It would be a very small site with very little scripting behind it ( I assume). She likes the idea of having a shopping basket, so thats what i need to do. Without cheating and using paypal, how would I go about setting up a basket system? Taking credit card details is preferable, but not essential if its too much bother with security issues. All I really want is to be able to accumulate product details that my boss can recieve along with contact/address details to ship out. I would love to do it in Flash as I do with everything else if it’s all the same, but I’m thinking i should do it in HTML as its my first try. Thanks in advance all.
