Go to your dashboard and click on design. This will bring you to the layout of your blog. You can add gadgets or move them around. Just click and hold a gadget from the sidebar and move it to where you want it. If you want to create a new gadget just click on add a gadget in the area where you want it to be (you might have to move it around to get it exactly where you want it when you are done).
