Does anyone know of a simple way to make a new font along the lines of webdings, etc. or if it is even possible? I've always been interested in codes and have been writing various symbol alphabets which I would like to be able to use on a computer.

I've searched on google but the only things I found were expensive programs for making real fonts. Basically I just want a way to type a letter on the keyboard and have it come up with some symbol that I make in MS paint and assign to it. Any ideas?
