Those basic smooth wood grips would be pretty easy if you've done any wood working at all and can run a few basic hand tools. You just need to find a source of the exotic hardwoods that provide that sort of figure. For example the stuff in your last post looks like it could be a lighter and more red cocobolo although it's usually a little more dark in the red parts.
For your gun I think there's a lot to be said for a more whitish/honey coloured wood to go with the matt chrome. Unless you want the contrast then go with a darker color.
