title: How to make a GUI for bash scripts?
body: <p>I want to make some graphical dialogs for my script but don't know how.
  I hear something about GTK-Server or something like that.
  If someone knows how to link Bash with tcl/tk I also be satisfied.</p>
  
  <p>Please do not post something like "change to C++" because my project
  must be a script in Bash; there are no other options.</p>
  
  <p>Any ideas?</p>
  
  <p><strong>EDIT:</strong> 
  Thanks for answers but I don't want "graphics" as in colors in the console, but graphical windows which I can move, minimize etc.
  I will test <code>xmessage</code>, but I don't think that will be what I am searching for.</p>
  
  <p><strong>EDIT 2:</strong>
  I don't want make a simple dialog like yes/no, but some interface like progress bars and buttons, something like a game.</p>
