Go ahead, man, and learn real notation.
It is really easy.
What you want to do is a very primitive way of notating - for people who think of themselves as dumb. They aren't dumb, but somehow they think that some things are too difficult for them.
The "normal" notes (without sharp or flat) represent the white keys on the piano. If one note is on a line, the next note is in the interval between that line and the next, the next note is on the next line and so on. If you aren't experienced, you have to count a little to find the position of the next note, but that's all!
Just look into some sheet music so that you know how many lines there are, how the clef looks, how the notes look exactly and so on.
