title: Best language for adding a GUI to a C++ software
body: <p>I've written a C++ software that can be used from the comand line and that, obviously, can be compiled and executed in different platforms (Linux, Windows and Mac).</p>
  
  <p>This software in particular is very simple, it just displays a menu in the command terminal with a few options, takes input files (.csv) acordingly, runs in a few seconds, and prints back output files (also .csv).</p>
  
  <p>Now I would like to write a platform-independent GUI for it without changing my original source code. </p>
  
  <p>Which is the best language? C++? Java? Does anybody have experience or recommendations on this?</p>
  
  <p>Thank you very much!</p>
