shopping carts

i am looking for a tutorial that will allow me to put a shopping cart on a web page.  it is a small cart and i have poor at best coding skills so it needs to be self explanatory and highly intuitive. is there such a beast? i am not sure what the server will be at this stage. i would like check boxes next to product image and and have it index and total order. i am treading water on this as never had to do it before.

thanks in advance.
