Currently popup panel doesn't work properly, However you can make your own custom panels which can be made to popup on different events using client handler or server handler.

Here is a rough code which will show you a demo for a popup triggered on a click event using client handler.

function doGet(){
  var app = UiApp.createApplication();

  app.add(createMaskPanel_());//this is used to make poup panel modal

  var mainPanel = app.createVerticalPanel();
  app.add(mainPanel);
  var btn = app.createButton('Open poup');
  mainPanel.add(btn);

  //Makke a panel for poup and add your popup elements
  var popup = app.createVerticalPanel().setId('popup').setVisible(false)
  .setStyleAttributes(
    {'position': 'fixed', 
     'border' : '1px solid black',
     'top' : '40%',
     'left' : '43%',
     'width' : '150', 
     'height':'150',
     'zIndex' : '2'});
  popup.add(app.createTextBox());
  popup.add(app.createButton('Close').addClickHandler(app.createClientHandler().forTargets([app.getElementById('mask'), popup]).setVisible(false)));
  app.add(popup);


  btn.addClickHandler(app.createClientHandler().forTargets([app.getElementById('mask'), popup]).setVisible(true));

  return app;
}

function createMaskPanel_(){ //Called when the setting UI loads, initially it will be invisble. id needs to be made visible
  //by accessing its id "mask"
  var app = UiApp.getActiveApplication();
  var mask = app.createVerticalPanel().setId('mask').setSize('100%', '100%') //maskPanel to mask the ui
  .setStyleAttributes({
    'backgroundColor' : '#f4f4f4',
    'position' : 'fixed',
    'top' : '0',
    'left' : '0',
    'zIndex' : '1',
    'opacity' : '0.5'}).setVisible(false);
  //Added a dummy element so that it spans to whole window.
  //don't know why but it works
  mask.add(app.createLabel('SBC Technology')
           .setStyleAttribute('color', '#f4f4f4')
           .setStyleAttribute('opacity', '0.5')); 
  return mask;
}
