    I think rather then creating main in public class SS extends Applet you have to create init() method .

    public class SS extends Applet
 { 
   /**
    * 
    */
   public void init() {
     win1 bb = new win1(); 
     getContentPane().add(bb )
   }
}

    But First you have to go through basics of applet How to Make Applets
