If you purchased a hosting account, or VPS/Cloud/Dedicated server with godaddy you are free to build your site any way you like. Even the Wordpress managed hosting allows you to add HTML/PHP code to customize your site.

The website builder is a great tool for building websites without having to know how to code. You can use oldschool Frontpage, Dreamweaver or any other webpage builder to code your site.
