Creating a single product Ecommerce site

i need to build a single product store front. can someone tell me if it is possible to do this with wp templates and plugins (without having to edit too much code) or if i am better off purchasing a packaged solution?

i have my domain and host but now i am struggling with how to get over the setup hump.

if you have experience with any particular templates or themes that you feel are particularly easy to work with, i’d love to hear about it. or…if you can point me to a resource for more information that would be great.
