Select 2 colors the way I described above, making it your primary and secondary color.
Now, select the pen tool, and click that circle in the top-window. now make a circle in the middel of the canvas, by holding shift while dragging. Move the circle around a bit, untill it is centered.
Duplicate the shape-layer and select the selection tool. Free transform the path, by right clicking the shape and selecting free transform.
Now, hold down shift and alt, and size the new circle down to about 2/3rd of the original size.
Double click the fill color in the layer pallete, so you can change the color of the shape.
Set it to the other color you picked earlier.
Repeat this step, so you have 3 circles, but give the inner circle the same color as you gave the background.
You will now have something that looks like a wheel or something
