It can be done, but it's ugly...
Add in a listener to your topmost JFrame to sense when the focus is lost, since this happens when a help window comes up. When the focus leaves the main window, check all the windows that are up to see if one is a help window. If so, this will give you a reference to the help window and you can drill down to change what you want.
Here's an example that changes the icon and removes the borders from the javahelp buttons.
WindowListener wndCloser = new WindowAdapter() {
          //A necessarily roundabout method to affect
          //look and feel aspects of the javahelp viewer.
          //(there is no way to get at these components directly.)
          //When the main frame loses focus, it may be because
          //the help viewer was brought up. Look through all
          //the current frames to see if one is a help viewer.
          //If it is, change the look of the help viewer
          //to what we want.
          Frame m_helpFrame = null;
          public void windowDeactivated(WindowEvent e) {
          if (m_helpFrame != null)
               return;
          Frame[] frames = getFrames();
          for (int k = 0; k < frames.length; k++) {
               if (!(frames[k] instanceof JFrame))
               continue;
               JFrame jf = (JFrame)frames[k];
               if (jf.getContentPane().getComponentCount()==0)
               continue;
               Component c = jf.getContentPane().
               getComponent(0);
               if (c == null || !(c instanceof JHelp))
               continue;
               m_helpFrame = jf;
               //now that we know the Frame, we can change the title icon
               final Image image2 = <your icon here>
               m_helpFrame.setIconImage(image2);
               JHelp jh = (JHelp)c;
               for (int s=0; s<jh.getComponentCount(); s++) {
               c = jh.getComponent(s);
               if (c == null || !(c instanceof JToolBar))
                    continue;
               JToolBar jtb = (JToolBar)c;
               //now that we've accessed the toolbar, we can
               //modify the look of the buttons.
               for(int i=0; i<jtb.getComponentCount(); i++) {
                    Component comp = jtb.getComponentAtIndex(i);
                    if(comp instanceof JButton) {
                    JButton button = (JButton)comp;
                    button.setBorder(null);
