This isn't anywhere near a complete GUI, but I figure someone may find it handy anyway. It's sort of a modern take on the old Final Fantasy style blue box with a white border.
Contains transparent PNG and original SVG source image. Created in Inkscape, which is the most awesome vector editor ever. :)
I may update this later.
