The defn wrapping the call to proxy basically is the constructor, so you
wind up with something roughly like

(defn get-window []
  (let [this (proxy [Window] ["My Window!"]
                  ; any methods you want to override on Window go here
                  )
    ; stuff making panels goes here
         ]
    (.addComponent this horizontal-panel)
    this))

Note, I'm calling a variable 'this' but it's *just a variable, the only
reason I called it 'this' was to make it look more like the java version.
