There can be only one `Tkinter.Tk` instance per running program.  Other
top level windows have to be `Tkinter.Toplevel` instances.

And you should reconsider your usage of classes.  You are just abusing
them as containers for functions without using `self` really.  And you
should pass the instance of the parent widget as first argument to
constructors of widgets.  Otherwise the very first, i.e. the `Tk` instance,
is assumed, which is not true for the widgets that should appear in the
`Toplevel` instance.
