You can add a "Help" button that opens a URL to GenericDialogs. With v1.44c and later, you can specify the font used to display the error message and the label used by the "Help" button. Here is an example:

   void error(String title, String message) {
      GenericDialog gd = new GenericDialog(title);
      Font font = new Font("SansSerif", Font.PLAIN, 16);
      gd.addMessage(message, font); // requires 1.44c
      gd.addHelp("http://rsb.info.nih.gov/ij/");
      gd.setHelpLabel("More Information"); // requires 1.44c
      gd.hideCancelButton();
      gd.showDialog();
   }
