You can connect a Godaddy domain to your store no problem, but to your question about connecting your domain to a specific page, would not be. You can connect a primary domain and then up to 10 subdomains which can point to your store, so if you meant that, then I guess it is possible. You can see the guide for how to connect a third party bought domain from Godaddy here.
Just to confirm what exactly you meant, if what I said didn't answer the question!
