iappscrazy, if you search for "chess" in 2d art you'll find a few complete pawn sets and boards. you could use those as placeholders (i think they actually look pretty decent).

There are lots of chess resources, but if you need high resolution you may render these:

If you want I too can render them for you, just specify the size and perspective.

I'm not sure I understand the problem.  Elements to make your own GUI are common enough and chess sets aren't hard to find either.  Here's mine, it comes with the tiles to make a board.  http://opengameart.org/content/boardgame-tiles
