I think you should create a custom CheckButton class  that packs a
Checkbutton without text and a separate Label into a Frame, like this
example (which is mainly stolen from ScrolledText.py):

from Tkinter import *

class CheckButton(Checkbutton):
    def __init__(self, master=None, **kw):
        self.frame = Frame(master)
        self.label = Label(self.frame)
        self.label.pack(side='left', fill='x')
        if kw.has_key('text'):
            self.label.configure(text=kw['text'])
            del(kw['text'])

        Checkbutton.__init__(self, self.frame, **kw)
        self.pack(side='right')

        # Copy geometry methods of self.frame -- hack!
        methods = vars(Pack).keys() + vars(Grid).keys() + vars(Place).keys()

        for m in methods:
            if m[0] != '_' and m != 'config' and m != 'configure':
                setattr(self, m, getattr(self.frame, m))

    def __str__(self):
        return str(self.frame)

if __name__ == '__main__':
    root = Tk()
    c = CheckButton(root, text='foobar')
    c.pack()
    root.mainloop()

You humans have that emotional need to express gratitude.  "You're
welcome," I believe, is the correct response.
