Why not create a 10x10 array to hold the pointers to the buttons? The 
Object that btnArray[0][1] would point to would be the button at that 
grid location.

Each button can be its own listener and change its own color by waiting 
for the Action Event to be generated when a user clicks it. By doing it 
that way you don't need to know what the x and y values are. Each button 
changes itself and would implicitly know what to change.

I personally don't understand what the above line is supposed to do.
