Setting up a web server

I would like to run a home website server so I can host my website. I already have the dyndns set up and when the url is typed in my live webcam shows up so I know port 80 is open. I just want my website to load when the url is entered. Any help? I have available, xaamp and jsas as well as filezilla server. My ISP allows home servers and I run win xp home sp3. I am aware of the security issues, I just need help directing incoming http requests to the folder where my site is indexed. Thanks for any help.
