I would think any graphics program like Photoshop, PaintSHopPro, and I think Fireworks ,  etc would do that. Perhaps there is a CoffeeCup program that would do it ?
Just some suggestions 

Maybe ReTodd will come by here and post what he used  (I think he made those ? )

I am generally a big illustrator/photoshop user, but I happened to make all the banners in Fireworks.  The effect is usually called a gel effect or glass, but I tend to make it simpler without inner shadows or shading.



Here I use a solid background and overlay a white ellipse (others I use a rounded rectangle) with the transparency set between 10 and 26, depending on the background color. Really simple, but a pretty clean effect.

For the ones like this:


I took a square, used the circular seclection tool and subtracted it, creating the arc, and set the transparency.

Hope this helps, and glad you like the banners. They aren't super snazzy, but that's not what I was going for anyway.

dang I need a better monitor (and/or better eyes) because I can barely notice what you are talking about in those images...

I make vista style glass effects

After checking out this thread - I have the sudden urge to go spruce up my own banners and graphics.

I like you glass styled graphics, and would love to have something similar for my website logs.
I need 3.
One for Ninja Success.com
One for MyCFOontheGo.com
and one for getrichgeek.com.

I'm willing to pay for something I like.
