I used photoshop to make it, but you can actually use any free online image editor with layers (like sumopaint) so you don't have to install a program to make one.
Just use any wallpaper you like (if you use sumopaint, go to file->open from...), then add text as a layer and position how you like.
If you want to maximize text space, use PrtScr on your keyboard and paint to save a picture of your desktop with poker tables open. Open this picture in sumopaint, ctrl-A to select all, ctrl-C to copy, then open the wallpaper you like, ctrl-V to paste, lower opacity of pasted desktop layer to have a visual what space is usable with tables open. Obviously you want to use a wallpaper in sumo that is the same size as your desktop resolution.
You can even save the finished file in sumo format, so you can edit later, just like photoshop.
If you want a neat desktop without clutter, you want to keep all shortcuts in the taskbar. The default W7 taskbar is crap though, and you need to tweak it a little bit.
1.) unlock your taskbar
2.) right click your taskbar -> Toolbars -> New toolbar (make and select a new folder, this will contain all shortcuts of said toolbar). Toolbars are like containers in your taskbar that contain shortcuts.
3.) right click the new toolbar -> disable "Show Text" and "Show title"
4.) drag the toolbar handle all the way to the left, takes a bit of playing around to understand how they work. Just play with the handles.
5.) drag shortcuts from desktop to toolbar. You can have multiple different toolbars, one for games, one for apps, one for drives etc.
