I know it is possible to create fonts from a bitmap image which contains all the characters. I’ve been looking for a tutorial but could not find any…
I made a small lib based on DFont using SDL and SDL_image to use bitmap fonts easilly (in SFont format), you can look at the code to give you an idea :

(get SDL and SDL_image from www.libsdl.org if you want to try it)

Not an advanced question but…
You can find a good tutorial here
You will also find a tool to make the bitmaps in Nehe’s tools/downloads section.
