You are installing Apache HTTP Server (wich is a http server) and PHP5 on a IIS (Wich is an http server for windows)
One of the easiest way to have a server up and running in windows is through http://www.wampserver.com/en/
So, uninstall all you installed on your question and use Wamp to manage the server with PHP and Mysql runing without more problems.
Of course, you can install all by your own, but since you want just a server runing, this one will help you to start fast.
Wamp lets you control the software versions, so you can try different php versions, apache versions, etc.
