You just bind a callback to the right-click and use it to post a Menu at 
the appropriate location, which you can get from the event's x_root and 
y_root fields.

My RO python package includes RO.Wdg.CtxMenu which will add a contextual 
menu to any widget.
<http://www.astro.washington.edu/rowen/ROPackage/Overview.html>
It is available from PyPI. RO.Wdg also includes a set of widgets that 
support contextual menus and "hot help".

In that package I bind to "<<CtxMenu>>" and then use another bit of code 
to send the <<CtxMenu>> event in a platform-independent way. When the 
event fires the following occurs:
    def __postMenu(self, evt):
        """Posts the contextual menu"""
        menu = self.ctxGetMenu()
        if menu.index("end") != None:
            menu.tk_popup(evt.x_root, evt.y_root)
