Build a Wordpress wrapper for WildWestDomains reseller basic

I have a reseller account through WildWestDomains and it has a really lame inerface. it always takes you to a [login to view URL] link and those layouts are super lame. There is a way to integrate a wordpress site as a wrapper for your storefront so only the actual transaction and account management happens on the crappy [login to view URL] site. I need wordpress made into this functionality. i have purchased elegantthemes and have chose one to be my site, it will need the integration. An example is having the ability to search for domains from the wrapper, and view all plans and such without having to go to the lame site.
