Design web application buttons

We need new buttons created for our web application. We need to be able to duplicate easily and edit so they will need a text layer as well. We want all text in the buttons to be centered and evenly spaced within top to bottom. Current button images are 145x25 or 108x25. We think we need a third size for a smaller number of characters too. Current buttons and current color is #A6BDCE Please see attached document for current and sample images as well as the list of buttons to be re-created.
