Creating a customized login page

Hello.

I have just started learning PHP. I’m am wondering is it possible for me to create my own login page, in replacing the one at https://email.secureserver.net/login.php

The URL above is the login page provided by my email provider.

What I wanted to do is to create a login page of my own in my website that can enable me to login directly to the email account when I keyed in the username and password.

Just wondering is it possible to do so? I yes, I would be grateful if you can point me to where I can get more information in creating this login page.

Thank you!
