Ok. I understand! Use google-translate too
Briefly, you can use Inkscape or Xara Xtreme to drawing, then add gradients, and the diffuse light (blur, "outer glow", "edge glow", etc.) in GIMP or Photoshop.
Or you can create the whole thing in Inkscape or Xara, but I think it's more complicated.
If this is so little, a few days (weeks
) later I make a tutorial, if you tell me which software you have.
