I have been using this code to implement a Popup JDialog of sorts, like what you see when your anti-virus is scanning your system or updates itself:

import java.awt.*;
import javax.swing.JDialog;
import javax.swing.JLabel;

public class PopupDialog extends JDialog {

    public PopupDialog() throws HeadlessException {
        createUI();
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                PopupDialog popupDialog = new PopupDialog();
                popupDialog.setVisible(true);
            }
        });
    }

    private void createUI() {
        setTitle("Popup Dialog");
        setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);

        addComponentsToFrame();

        //This call will give screens viable area, which takes into account the taskbar, which could be at the bottom, top,left or right of the screen.
        Rectangle maxBounds = GraphicsEnvironment.getLocalGraphicsEnvironment().getMaximumWindowBounds();

        //get screen size
        int sWidth = maxBounds.width, sHeight = maxBounds.height;

        setSize(275, 225);//set frame size
        Dimension appDim = getSize();
        //get app size
        int aWidth = appDim.width, aHeight = appDim.height;

        //set location like a tooltip would be except its a custom dialog like an AV
        setLocation(sWidth - aWidth, (sHeight - aHeight));
    }

    private void addComponentsToFrame() {
        JLabel label = new JLabel("Popup Dialog");
        getContentPane().add(label, BorderLayout.CENTER);
    }
}

But my question is: is there any class or package in java that will do this for me? and if not how would I go about allowing the JDialog to slide up from the taskbar (or offscreen)? or somehow become visible in a slow manner like a ToolTip Popup would from the system tray. Thanks.

EDIT The reason i want to use a JDialog or Frame is because i want to be able to fully skin the Popup window, using setUndecorated(true); and adding custom exit icons, backgrounds etc
