The preferred way is to use use the appearance system 
<http://qooxdoo.org/documentation/0.8/ui_appearance> and redefine the 
appearance key "window/title":

    "window/title" :
    {
      style : function(states)
      {
        return {
          alignY      : "middle",
          font        : "bold",  // <-- the font
          marginLeft  : 6,
          marginRight : 12
        };
      }
    },

This will change the font for all windows. If you only want to change 
the font for this specific window you can use:

win.getChildControl("title").setFont(font);

Font is either a font name defined in the font theme 
(qx.theme.modern.Font) or an instance of qx.bom.Font 
<http://demo.qooxdoo.org/current/apiviewer/#qx.bom.Font>.

Best Fabian
