Sorry for the misunderstanding. Your first post said that you made the database in/using Dreamweaver. Thanks for clarifying that you actually made it your cPanel instead.
I don't use Dreamweaver, and I know nothing about it. If there is a way to create a login script using that program, then you'll need to ask help from the 3rd party scripts section of the forums, or ask for help from Dreamweaver's support site. We can't promise any support for 3rd-party scripts here in this support forum, only for helping with problems concerning the hosting account itself.
