Yes. One of the major drawbacks of using the display architecture as a
GUI toolkit is that the only form of user input available is
unmodified mouse buttons. Tcl/Tk has no such restrictions; you can
receive key events, as well as obtaining the modifier state for mouse

There's no reason why a decent GUI can't be made which only uses the
left mouse button, with the right mouse button reserved for a context
menu, and the middle button only used for functionality which can be
obtained by other means. All modern Windows applications manage to
work that way.
