GridBagLayout and widget replacement

Is there a way to lock or fix the cell size of a GridBagLayout after I've used it to add components to a JPanel? I need to dynamically replace components in the panel, but removing a component and adding a different one causes the grid to resize. For example, replacing a JComboBox with a JLabel would make that row in the GridBag shrink vertically, because the JLabel is shorter than the JComboBox - this messes up the spacing between other components in the grid. I'd like to prevent the resizing, if possible.

thanks in advance for any help.
