Active Desktop Stuff

I need some help, and I dunno were this belonged, but since it is asking about the code invloved in HTML docs, I put it here.

Basically I am wanting to build a desktop in which I create LINKS on my desktop instead of using ICONs. I know how to set that stuff up, but what I don't know how to do is to create a link that will allow me to open a program from a webpage.

Also, how does a mouse over work, what is the code used to do this.

NOTE/FYI, I used to be able to do this stuff, but it has been over 2 years now since I last even created a hyper link, so I need a refresh in my memory
