Made these buttons following the tutorial How to Create a Slick and Clean Button in Photoshop as written by Jacob Gube. Did sort of cut out of few steps to simplify the process and have only made a one-state button. If you like the buttons feel free to download and use them. The full button looks as shown below. The gallery images are cropped so click them to see the full-sized buttons.
I’ve included the PSD button in the Download Package
so you can play with it to create your buttons in your preferred colors. You could also just adjust the hue/saturation of the png buttons to make more colors.
Thanks to sixrevisions.com for the tutorial.
