With the game screen where it is and depending where you position your devtool window it'll be pretty hard to find a background that fits just the way you want and pleases you at the same time.

If i may i'd advise just doing how you would make a normal background like for your desktop by composing different images (with photoshop or paint or any image editing sftware of your preference) and leaving empty spaces where your game window and panel will be.

Then just upload it somewhere (imageshack or whatever), i use "puush" to just auto screen and upload what i end up with and just copy/paste the link it gives me and it works fine.

You can check my post lower to have an example, i can also post the plain background so you can see the spacing and stuff if you'd like.

Try messing around with it, it's fun.
