You could use an existing template from Encore that has video buttons, then go into Photoshop and just remove them, retaining the rest of the design. You would probably want to chose a template that would still look appropriate after removing the video buttons.
While not exactly free, we offer DVD and Blu-ray motion menu templates for use in Encore and DVD Studio Pro. Our menus are used by nationally acclaimed wedding filmmakers and video production companies. We offer them at an extremely good price, and might have just what you are looking for.
