I want to use my own frontend for my website, and only use Magento for the cart and backend. Most of the site is not a commerce site and I don't want Magento taking it all over. I've read about how to do this with Zen Cart, and I was wondering if it's feasible to do with Magento as I much prefer Magento's backend.
Basically I want to figure out how Magento adds items to the cart and use that code in a button on my website while using my own theme. Then I want to use the code that displays the cart and allows you to checkout in another page.
I'm not even sure this is allowed with Magento's licensing.
