If you've ever wrangled a user interface, you've probably heard of Fitts' Law. It's pretty simple -- the larger an item is, and the closer it is to your cursor, the easier it is to click on. Kevin Hale put together a great visual summary of Fitts' Law, so rather than over-explain it, I'll refer you there.
The short version of Fitts' law, to save you all that tedious reading, is this:
* Put commonly accessed UI elements on the edges of the screen. Because the cursor automatically stops at the edges, they will be easier to click on.
* Make clickable areas as large as you can. Larger targets are easier to click on.
