Maybe you could use a Checkbutton with indicatoron=False, as in:

import tkinter

root = tkinter.Tk()

def toggle(button, variable):
    if variable.get():
        button.config(text='On')
    else:
        button.config(text='Off')

v1 = tkinter.BooleanVar()
v1.set(False)
b1 = tkinter.Checkbutton(root, text='Off', variable=v1, indicatoron=False,
                         selectcolor='', command=lambda : toggle(b1, v1))
b1.pack(padx=50, pady=50)

root.mainloop()

The button in this example looks tiny compared to a Button(), but this
could probably easily be fixed. Unfortunately there does not seem to be a
indicatoron Option for the ttk.Checkbutton though, and I am not sure how
good or bad this will look on windows.
