If you move your domain pointing to your Website Builder website to cPanel your existing website will no longer be available. Unless you are planning on creating a new website on your cPanel you probably do not want to do that. I think that what you really want is to have a simple URL that people can access? If I may suggest the GoDaddy URL Shortener for your use... It will give you a short URL to present, email, text... to your clients. Check out URL Shortener Help and get your own short URL associated with your GoDaddy account. I hope that helps?
