If you do want to install PHP and MySQL on their server there are many preconfigured packages available known as WAMP.
I use the UniformServer but many are fond of XAMPP. Both have Apache, MySQL and PHP preconfigured. You just copy the directory onto that machine, and run - either as seperate programs or as system services. No need for installation or manual configuration (which is a real pita I might add).
My helpful sig is on vacation trying to loose some weight. It got a bit fat and caused a few problems but it will be back at some point!
