Well, just for fun, testing on Linux:
Logitech G500:
   Button 1 : left mouse
   Button 2 : center button (pushing the mouse wheel down)
   Button 3 : right mouse
   Button 4 : mouse wheel up (rotation)
   Button 5 : mouse wheel down (rotation)
   Button 6 : mouse wheel left (this is a click, not a rotation).  This
button repeats when held left.
   Button 7 : mouse wheel right (again, a click, not a rotation)  This
button repeats when held right.
   Button 8 : lower button on left side
   Button 9 : upper button on left side
   Button 10 : center button on left side

So using button 6/7 for horizontal scrolling would be quite usable.  Like
4/5, the 6/7 repeat
generates press/release pairs.  None of the other buttons repeat.

On Mac OS X:
Logitech G500:
   Button 1 : left mouse
   Button 2 : right mouse
   Button 3 : center mouse (note reversal from Linux/Windows)
   Button 4 : left side lower button
   Button 5 : left side upper button,
The left mouse wheel, right mouse wheel and left side center button  do not
register.
I forgot to actually test a bind to <MouseWheel>, but we can assume it
works.

Windows:
Logitech G500:
   Button 1 : left mouse
   Button 2 : center mouse
   Button 3 : right mouse
   Mouse Wheel up and down
Left mouse wheel, right mouse wheel and the three left side buttons do not
register.
In this case, I am just using whatever defaults are in the logitech
software.

The upper and lower left side buttons are assigned to "forward" and "back"
and windows
is probably intercepting these assignments.

The left and right mouse wheel are assigned to "scroll left" and "scroll
right".  Maybe
windows is also intercepting these assignments?  They work in FireFox, so
Windows must
be seeing them, but Tk does not.
