No ideas sorry dude.
If you have developer tools installed , I'm sure you can make a one-window app with brushed metal, no interface elements.
Another suggestion is to open Photoshop. Just make a greay rectangle. Go into blending options. Click bevel and emboss. Then click texture and pick the sorta yellow/mustard colour one. Not brushed metal, but in grey it looks sorta close.
Sorry I can't be of any more help.
