Open up Microsoft Paint and start a fresh tileset. Although, I don't recommend it... unless you're a skilled pixel artist of some sort.
Alternatively you could go to a website and download a image editing application which goes under the name GIMP and use that one. It won't take long until you have managed to pull off a tileset, just let your creativity flow.
Just remember that each tile on the tileset are exactly 32 pixels in width and 32 pixels in height.
You could start a tileset with the size (448x224) that is 14 tiles wide and 7 tiles high, it'll be a good starter tileset to work on. Good luck mate.
