回答1:

I think there is no chance. You need to add them one by one. frame.add(...); frame.add(...);
I don't clearly understand what you want as result, but using GridLayout(3, 3) with only 2 panels is the same as use GridLayout(0, 2).
P.S. Check out GridBagLayout - it can be more useful for you.

Depending on what you want to do, you could add "dummy" components (like a JLabel) to the cells you don't want to use. If I recall correctly, GridLayout will layout in col/row order

So of you wanted to add a component to the second column on the second row, you would have to add four JLabel's first, do pad out the layout
