Windows 7 has a an application called Sticky Notes, which does just that. The contents and layout of the stickies are stored in a single file: %APPDATA%\Microsoft\Sticky Notes\StickyNotes.snt
If you wish to backup or transfer your sticky notes, this is the file you need. When restoring, simply place the file in the same location and you're done with it.
