You can create a new php page that uses the same cart template structure if you look at a php page that already exists, use the same include lines at the top, include the last few lines that points to the Smarty files, create a tpl for that page, then add that new entry to customer/home_main.tpl.

As with creating any new php pages, you'll want to ensure that your site stays secure. That's why it's typically best to stick to pages that already exist when you can.
