Build a Raised Vegetable Bed

Question

What lumber should I use to construct a raised vegetable bed (4 feet wide by 16 feet long by 2 feet high)? If boards are 8 feet long and a foot wide, how do I connect them to make 16 feet? What about the corners? Should sides be reinforced? Can I use 4 x 4 posts that are not treated?
