My simple GUI source Code

package com.StockWatcher.client;
 
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.FlexTable;
import com.google.gwt.user.client.ui.HorizontalPanel;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.TextBox;
import com.google.gwt.user.client.ui.VerticalPanel;
 
public class StockWatcherApplication implements EntryPoint {
 
  private VerticalPanel mainPanel = new VerticalPanel();
  private FlexTable stocksFlexTable = new FlexTable();
  private HorizontalPanel addPanel = new HorizontalPanel();
  private TextBox newSymbolTextBox = new TextBox();
  private Button addStockButton = new Button("Add");
  private Label lastUpdatedLabel = new Label();
 
  /**
   * Entry point method.
   */
  public void onModuleLoad() {
    // Create table for stock data.
    stocksFlexTable.setText(0, 0, "Symbol");
    stocksFlexTable.setText(0, 1, "Price");
    stocksFlexTable.setText(0, 2, "Change");
    stocksFlexTable.setText(0, 3, "Remove");
 
    // Assemble Add Stock panel.
    addPanel.add(newSymbolTextBox);
    addPanel.add(addStockButton);
 
    // Assemble Main panel.
    mainPanel.add(stocksFlexTable);
    mainPanel.add(addPanel);
    mainPanel.add(lastUpdatedLabel);
 
    // Associate the Main panel with the HTML host page.
    RootPanel.get("stockList").add(mainPanel);
 
    // Move cursor focus to the input box.
    newSymbolTextBox.setFocus(true);
 
  }
 
}
