Making a login/register script won't be difficult.
Create a database table with fields like id, username, password, email, etc.
Make a form for register, get values in a php file, insert them into database.
For login, make another form, lookup for user based on username, verify whether passwords are same, make a session to denote the user is logged in.
You should add some security like validating user input through mysql_real_escape_string, hash+salt the passwords, etc. If you don't know how to do the things i mentioned, then you should first learn PHP&MYSQL basics.
