White Stroke Buttons

Bars:
Step 1:
Open up a fresh document, any size will work, but I've chosen 600x300px so it fits on this screen good. Fill the background a light grey. I used the color #e5e5e5.

Step 2:
Create a new layer and set your foreground color to #3e3e3e. Now grab the rounded rectangle tool with a radius of 5px. Make a rounded rectangle the width you want your bar and about 100px in height. The height doesn't have to be exact, we will be trimming it.

Step 3:
Grab the marque tool and make a box around most of the rectangle (leave arround 60px out on the top). Press delete.

Step 4:
Now lets apply stroke and gradient overlay to our bar. Open up blending options and use the following settings.



Step 5:
Alright, now that we have out base set up, let's add the stroke to make this thing shine. Create a new layer and zoom in so you can see individual pixels. Now grab a pencil tool with a 1px white pencil. Now you're going to draw a one pixel like across the top (1 pixel down) and round the corners by one. Take a look at the picture, you'll know what I mean.


Step 6:
Set the layer mode of the white stroke to overlay and lower the opacity as needed.


Step 7 (Optional):
We now have the basic bar complete. At this point you can add things to make it look a little bit different. Drop shadow with pattern overlays tend to work great! Here's a few variations:

You can also change the colors. Pretty much any color will look good. I'll use a different color for buttons.
