Step 1.
Start off by making a new Photoshop document. Choose the rounded rectangle tool, set the radius to 12 pixels, and create a wide rounded recntalge, as shown below, It doesn’t matter what colour it is because we’ll be creating a gradient with the shape next.

Step 2.
Choose dark maroon (6f1300) for the foreground color and a lighter shade for the background color (c82e00). Make a selection (select > load selection) using the rectangle
(a)

(b)

Step 3.
Choose the linear gradient, cirlcled in green (a). Open the gradient editor, by clicking on the sample gradient, and choose “foreground to background” (b)
(a)

(b)

Step 4.
To create the gradient, drag form the top to the bottom of the selection, which should produce something like in the iamge below.

Step 5.
This is the 2nd part of this Photoshop tutorial, to create a menu bar. Next create a thinner rounded rectangle, and make a selection using it (select > load selection)

Step 6.
Set the foreground color to ff5d4f and the background color to e51301. Create a linear gradient on the thinner rectangle, by dragging from top to bottom(b)
(a)

(b)

Step 7.
Now merge (Layer > merge down) both of the rounded rectangles into a single layer (a). Use the rectangular marquee tool to make a selection (b). Create (layer via copy) new layer using the selection.
(a)

(b)

(c)

Step 8.
Change the color (Image > Adjustments > Hue / Saturation) of the copied part

Step 9.
I’ve changed the color to the color below,

Step 10.
Push the blue part up by 2 pixels using the UP arrow key. Copy (Layer via Copy) another part of the rounded rectangle. Use the transform tool (Edit > Free Transform) to increase the height to about 110% (b)
(a)

(b)

Step 11.
Next make another copy of part of the rounded rectangle, ajusting it’s color (Image > Adjustments > Hue/ Saturation.

Step 12.
Push the green part up by 2 pixels using the UP arrow key. You should now have 3 copy parts of the rounded rectangle.

Step 13.
This is the 3rd part of this Photoshop tutorial, to create a menu bar., where we’ll be adding the text and creating a reflection of the menu bar. Next, add some text using the the setting shown below (b) or your own.
(a)

(b)

Step 14.
Merge the 5 layers into a single layer.
(a)

(b)

Step 15.
Duplicate the menu bar layer from the layers panel , and flip it vertically (Edit > transform > flip vertical). Create a new layer above the menu bar and the duplicate. Make a selection using the rectangular marquee tool.

Step 16.
Choose the gradient tool (a), set it to the linear gradient and then open the gradient editor (b). Choose “foreground to transparent” (c)
(a)
