MySQL + PHPnuke = help

I'm a complete noob at this so bare with me...

I installed MySQL and it appears to be working fine. Created the Datebase using the "mysqladmin create" command and filled the database with tables using my .sql text file provided by PHPnuke.

I then edited the config.php file and added my username and password. However, when I open admin.php or index.php in IE, all I get is text.

What I need help on is where do I put all the PHPnuke files? Do I have to have a web server with MySQL enabled/installed or can I just use localhost on Windows XP like I have running now?

All the resources I find on the internet assume the user has some knowledge of MySQL and PHP. Are there any resources that explain it in more simple terms?
