I don't think there is support for background transparency in Tk.
The best bet is probably to try something like this:
from Tkinter import *
root = Tk()
img_off = PhotoImage(
img_on = PhotoImage(
c = Checkbutton(root, indicatoron=False, image=img_off,
selectimage=img_on, bd=0, selectcolor='', width=12, height=12)
If you need text next to the checkbutton, you can create a canvas text
element, instead of using the checkbutton's text option.

You'll learn something about men and women -- the way they're supposed
to be. Caring for each other, being happy with each other, being good
to each other. That's what we call love. You'll like that a lot.
