Lets start off opening up Photoshop and creating a new 1024×768px file and change the background layer to black. Make sure your black is in the foreground and then option + delete.
Now lets put some text in. Type in what ever you want, but we do want to keep it just white with no gradients or shadows or anything. You can also add an image but keep in mind that it needs to be just one color, and changed to white.
