Java swing question (programming)

[Tab]

I'm trying to go up the Java learning curve (finally), and am screwing around with layouts. I want to use a grid layout, and populate each "cell" with its own stuff. I understand that I need to insert panels into the grid, but from there I fail to connect the dots.

Let's say I have

mainContent =getContentPane();
mainContent.setLayout(new GridLayout(3,1));

Okay, so I have a 3-row grid.

Now what?
I want to stick some stuff into the first row. How would I do that?

cxPanel =new(JPanel());

cxNameLabel =new JLabel("Name");
cxAddressLabel =new JLabel("Address");

cxPanel.add(cxNameLabel);
cxPanel.add(cxAddressLabel);

??

How do I associate the panel to the particular position in the grid? Would the above work (well, I know it doesn't) - what am I missing here?

Thanks
