       WebView webView = new WebView();

                   webEngine.load("http://java-buddy.blogspot.com/");

           buttonHello.setOnAction(new EventHandler<ActionEvent>(){

               @Override

                   webEngine.load(urlHello.toExternalForm());
               }
           });
          
           toolbar = new HBox();
           toolbar.setPadding(new Insets(10, 10, 10, 10));
           toolbar.setSpacing(10);
           toolbar.setStyle("-fx-background-color: #336699");
           toolbar.getChildren().addAll(buttonJavaBuddy,buttonHello);
          
           getChildren().add(toolbar);
           getChildren().add(webView);
       }
      
       protected void layoutChildren(){
           double w = getWidth();
           double h = getHeight();
           double toolbarHeight = toolbar.prefHeight(w);
           layoutInArea(webView, 0, 0, w, h-toolbarHeight, 0, HPos.CENTER, VPos.CENTER);
           layoutInArea(toolbar, 0, h-toolbarHeight, w, toolbarHeight, 0, HPos.CENTER, VPos.CENTER);
       }
      
   }
  
}

In this case, a local hello.html is needed, refer to the article "Load local html in JavaFX WebView".
