If it behaves approximately the same as MAMP, you need to go into its preferences --or whatever your platform calls them-- and select a default directory.
You can never open the file directly from your desktop; it has to be done within the browser. Make a "WAMP site" or similar bookmark and you won't have to memorize the URL. (Mine's http:/ /localhost:8888/ That's the free version, where you can only use one domain at a time. I think the fancier version comes with a pseudo-DNS so you can do multiple domains.)
