Hey, there are many different ways you could do a login but each of them require a server-side language. These being php, asp, jsp and others, again with that would require a database program like MySQL, SQL, etc. Each server-side works well with a specific database usually, and php works with with MySQL. If you arent interested to learn a server-side you could check out http://www.hotscripts.com and see if there are any scripts that interest you, but if you are Google is your friend. as well as this site does have server-side sections where you can ask questions.
