Oh stop whining about the wallpaper, the idea is brilliant, unique and definatly something I would use. The wallpaper is something you can see on womans magazines and billboards anywhere.
If I knew anything more about android development other than the layouts are extremely frustrating when you come from a windows development background, I would tackle this myself.
This not a quite hard thing to do actually.
Draw the icons to the wallpaper of your screen size.
Set the shortcuts (or widgets like folder organizer if you want folders) with blank icon at the corners every page.
Set no scrolling wallpaper.
