GET Different Front Page

I once thought I need a different home page for different viewers. In best case those users have a GET parameter which decides which page has to be shown.

For Example: You go into WordPress and add a page with a name of your choice (in this case the page slug). I chose «music». Now if you want somebody view the music page you have the parameter http://www.example.com/?view=music. You can do this with every page you have.

In case you leave it empty nothing happen at all.
