Do you not use an Audio/Midi Editing program? You can then set up the whole lot as separate tracks!
You can then sing , play, click, dance along all at the same time!
Why do the notes in Paint ? PhotoShop is a much better program!!! LOL
Only kidding! there are free notation progs out there.....http://www.freebyte.com/music/#free_notation  for instance!

there is a program out called "power tab editor"...
I have not been able to get into it at all as of
yet.. will when the time's available.. it will allow
someone to write out guitar tab and then it will
convert it to treble clef musical score, save, print
out, and convert to a few rich text modes so it
could be sent as a file, or imported into something
else such as word or what ever will accept it and
convert it to their formats.. may be worth a try
if you are writing out guitar tab there bro.. it also
will help to get it to someone in sheet music form
also.. sure will just be the treble clef... but most
keyboardists - pianists will be able to arrange the
left hand - bass clef in their on interpretations...
but I know there are a few shareware programs
out there that you use staff paper type interfaces
to score your music..  saw a couple somewhere,
but unable to grab one or would have.. think I
was lurking around download.com, cnet.com
and a few of those type sites looking for other
programs.. just honestly don't remember..

why do a cat bites its tail?

try with handclaps and then singing. Many of bandamp members are able to realize a rhythm just by handclapping and whistling.
