Create a webview from a button in JavaFX - button

Question

I have the following simple code where I have an horizontal block where there are two buttons, the remain part is empty. Now, I would like to view a Webview inside the free part after the user press the "current" button. I already did something similar but I wasn't able to manage the layout because it was a Jframe + JavaFX. I thought to re-build totally in JavaFx , for this reason I want to put the webview in a jfxPanel(I think it's the best solution, any other suggest is really appreciate). I should see the webview when I press the button , in this case current, for this reason I create an handle. So, How can I do it?
Thanks in advance

Here is some sample code to get you started, it creates a couple of WebViews and toggles between them depending upon a radio button selection.
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.layout.*;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
public class CountThePeople extends Application {
private static final String CURRENT_URL =
"http://www.census.gov/popclock/";
private static final String PROJECTED_URL =
"http://www.sciencedaily.com/releases/2015/08/150810110634.htm";
#Override
public void start(final Stage stage) throws Exception {
WebView current = new WebView();
current.getEngine().load(CURRENT_URL);
WebView projected = new WebView();
projected.getEngine().load(PROJECTED_URL);
StackPane viewHolder = new StackPane();
ToggleGroup choice = new ToggleGroup();
RadioButton currentRadio = new RadioButton("Current");
currentRadio.setToggleGroup(choice);
RadioButton projectedRadio = new RadioButton("Projected");
projectedRadio.setToggleGroup(choice);
choice.selectedToggleProperty().addListener((observable, oldValue, newValue) -> {
if (projectedRadio == newValue) {
viewHolder.getChildren().setAll(projected);
} else {
viewHolder.getChildren().setAll(current);
}
});
choice.selectToggle(currentRadio);
VBox layout = new VBox(10, currentRadio, projectedRadio, viewHolder);
layout.setPadding(new Insets(10));
stage.setTitle("World Population");
stage.setScene(new Scene(layout));
stage.show();
}
public static void main(String[] args) throws Exception {
launch(args);
}
}
