Even though you drive me nutz... I'll post a suggestion.
You can use a product like 3m spay adhesive to affix your artwork to your control panel surface (after you print it out on paper/photo paper/whatever)... Then you can use light coats of clear coat to finish/protect it...
This also assumes you've already painted the base color or laminated it already... (neon green?!)
Good luck.
