Not sure what Tkclient() is... seems to be not child od Tk(), cause 
there is no getvar() function...
Anyway I am not able to run your script cause you used there both tabs 
and spaces for indentation. (see the row OPTIONS = 
["en","pt","es","it","fr","de"], how much it is intended....)

Shoudnt be there varValue = self.startw.getvar(name)? - just guessing - 
I can not check cause the indentation i scorrupted ;-)
