title: animating components in Jpanel
body: <p>I have this idea that I want to implement into my project.
  I know it is doable, but I do not know where to start.</p>
  
  <p>I have a JPanel, 
  in there will be a Jbutton , a JLabel, and a ComboBox, and a JtextArea.</p>
  
  <p>Originally, there is only the JtextArea and JButton on my panel.</p>
  
  <p>When I hit the button, the Combobox, and JLabel will slide in or fade in, or drop down, or event rotate in. </p>
  
  <p>So how would I accomplish this, I know I have to use graphic g, repaint(). It is easy to do the Jlabel but what about the combobox.</p>
  
  <p>Should I add the combobox and Jlabel into a separate Jpanel and make that panel animated in. but even that, I do not know how to make this panel in motion.</p>
  
  <p>Please help me on this, and example would be appreciated</p>
  
  <p>Thank you! </p>
