Can I have 5 panels in a row

Question

Is it possible to have 5 JPanels in a row in a single Frame? Heres my code you may get a better understanding of the question:

setLayout(new BorderLayout());
add(mainOrderInfo, BorderLayout.WEST);
add(meatPanel, BorderLayout.WEST);
add(cheesePanel, BorderLayout.CENTER);
add(ingrediantsPanel, BorderLayout.EAST);
add(addonsPanel, BorderLayout.EAST);

When the code is ran all I get are the meatPanel, cheesePanel, and ingrediantsPanel. I would like the mainOrderInfo to be to the left of the meatPanel and the addonsPanel to the right of the ingredientsPanel. I feel as though its simple a matter of code or ordering of code that I am not aware of.
