Here is a sample of a simple GUI asset that was just posted. This is a pack of 160 GUI objects with a wood background. The layouts for the wood are realistic but simple with a variety of different color schemes.
There are (4) different colors. (3) are for your basic normal, click and highlight where the other can be used for Inactive or to adjust the color scheme to whatever you would like with the color removed from it.
