Love it or hate it, the “Web 2.0″ look is everywhere these days, and if you are in the design or web line of work, you may find yourself wanting to (or having no choice to) create them at some point. I’ve collected a few tutorials that I think are worthwhile and fairly quick and easy on making Web 2.0-style buttons and shapes. I tried to stay away from Illustrator ones that inlcude a lot of transparencies – they gum up your file and can make it a nightmare to work with. So, without further ado:
1. Tutorial: How to create a shiny Web 2.0 button in Illustrator (graphics-illustrations)
Quick and easy with a nice result that can easily have other graphics added to the button area.

2. Shiny Buttons Without Blends or Transparencies in Illustrator (VecTips)
Another simple Illustrator tutorial, this time for rectangular buttons or shapes.

A similar effect as the above tutorial, but with a slightly different look, and this time for Photoshop.

4. Design a Glossy Download Icon (PSD Tuts)
A slightly more complex tutorial for Photoshop, but with a great result.

5. How-to Create a Web 2.0 button/icon (All4YourWebsite)
A really quick-to-make square button for Photoshop.

Hope these are useful to you!
