BAM! Transparency will not be an issue; can hook you up with transparent PNG versions of each + the original PSD so you can create any text you want in the same style!
Had an idea for you ptiteconne! I posted the identical version above with a white background, below I've posted it with a gradient background + "onclick" alternatives so when they press the button they see the response. I also added a little sharper variation at the end. You can have 'em all! You'll also get the font name, where to get it, the PSDs for all designs so you can create any text in these styles, etc.
