How to create new component in SWING?

Question

Hi,
I created a suggestion box using JTextField and JList. It's working nicely. I would like to Standardize those component into single component. so that i can add whenever i need suggestion box in my project anywhere. Can anyone give me a suggestion to do this?
- i want to create it like a normal components (JButton, JComboBox and etc). but it consist of two components.
- i need to create it's own inbuilt listeners like (MouseListeners, KeyListeners). (i can extend the JTextField class and implement KeyListeners in it).
- i like to add functionality like. (Whenever i type any character, then values for the corresponding characters are fetch from the DB and set into the Model).
Am just thinking whether i need to paint a component and add some AncestorListener. or else to extends the existing component. Kindly suggest me for this thing. Thanks in advance.

Mo

Thanks for your reply WalterLaan. If i use JPanel and i add some components like JTextFeild and i set JList for its Listener. Then it'll works with in the added JPanel. Not in the JFrame.
i can write Like...
class MyPanel extends JPanel
MyPanel()
super();
JTextFeild t = new JTextFeild();
add(t);
JList l = new JList(new String[]{"1,","2"});
add(l);
class frm
public static void main(String arg[]){
JFrame jf = new JFrame();
MyPanel mpl = new MyPanel();
mpl.setBounds(0,0,100,30);
jf.add(mpl);
So i can't able to see the added JList. Right???? How to i create a JList like a PopUp???
Kindly Guide me to invent new component. Thanks in advance.
