I just did a complete guide here: http://www.wordpressmax.com/how-to-install-wordpress If you need help let me know.
Create a folder called "blog" on your webserver. Unzip the WordPress package. FTP only the contents of the "wordpress" folder into your blog folder. Follow the install process.
Wait, it is so simple and there is a tutorial on their own official site as well. I know I ain't helping by crapping like this but seriously...
If you are hosting your blog site using cPanel with Fantastico feature, you can install any self-hosted Wordpress blog platform on your Domain within 5 minutes. cPanel > Fantastico Click Wordpress Click New Installation In Admin area > fill in all the required Usernames and Password (keep a copy in Notepad) Click Next till you Finish Installation Send a copy of the Wordpress Installation to your Email Account
