Multiple screens 1 monitor?

I have a lot of icons on my desktop. Some pertain to certain tasks i do. I know if you have multiple monitors you can extend the desktop. But is there any way I can edit the desktop in windows 7 so I can have multiple desktops that i can pan through for instance with 1 monitor. I'd like to click an arrow to go to the next desktop, then have a picture that says Songwriting , and then have my music making programs, then scroll to the next desktop and have one that says Games, and have all my game icons there? If windows 7 can't do this is there any cheap program that can?

Thanks that program is awesome!
