As I said you need to store user's role also in the database. When user logs in you can identify what is user's role from the database and show appropriate UI to user. I hope I am able make a point here. If you have implemented login functionality without role, can you share that code in the original question so appropriate solution can be provided

Create a database and store user information such as username, password, role etc in a table in database. Create Windows form application with login form. Write code to retrieve users information from database based on username and password user entered in the form. That's what you need to do to start with. Did you bother to search on Google? If not you should have done that. http://www.ittutorialswithexample.com/2015/01/simple-windows-form-login-application-in-csharp.html?m=1
