title: Can GTK work with a readline like library?
body: <p>Is it possible for a graphical GTK program, to also have a "command line interface" like those provided by <a href="http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html" rel="nofollow">GNU readline</a>, <a href="http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html" rel="nofollow">editline</a> or <a href="https://github.com/antirez/linenoise" rel="nofollow">linenoise</a>?</p>
  
  <p>How to deal with blocking gtk_main() calls, and blocking loop steps from those libraries?</p>
