If you only intend to support border and flow layouts, you could
reduce the verbosity by maps implying border layout and vectors
implying flow layouts. That approach would limit you to simpler
layouts, but your example would become something like this:
(deflayout frame
{:west gamepanel
:east (deflayout sidepanel
[nextpanel (JButton. "Exit")] :flow :trailing))
