idea for a guitar neck ui to remember notes.

Please get me started on this.

I desire to create a grid like ui
e.g = rows 6, columns 24
that should fit comfortably within the size of my screen
i would like each cell to be a radio button kind of ui element

the purpose of making this ui is to help remembering notes of guitar songs. ( for solo  notes only not chords )
my idea is that as i read guitar tabs i click on each corresponding radio button
such that if i click 4 radio buttons in series  - the neck should show last 3 radio buttons as selected

ie. when i click first radio - it should get selected
when second - 1st and 2nd should show selected
when third - 1st, 2nd and 3rd should show selected
when 4th - 2nd , 3rd and 4th should show selected.

regards,

sumit
