Xcode-Show and Hide windows with checkbox?

Question

I am making an applescript/cocoa application in Xcode 4.6. I in my Main Window, I have two windows that are hidden at launch ("Preferances", and "Advanced") and one window ("Simple") that is visible at launch. In the preferances window, I have a checkbox. I would like that box, when checked to display the "Simple" window, and Hide the "Advanced" window, and even when closed and relaunched, will remain how the preferances are, and not have to check the box everytime on startup of the app. Anyone know how to do this? Thanks!

Ok something isn't quit right

What do you mean by in the main window are two windows?  Also if the checkbox is in the preferences window and that is hidden at launch how do you get to it to check/uncheck it?
This checkbox basically toggles between the two windows? selected it displays the 'simple' window, when unchecked it displays the "Advanced" window?
This script
script AppDelegate
  property parent : class "NSObject"
    property ppw : missing value
    property isShowing : 0
          on applicationWillFinishLaunching_(aNotification)
  -- Insert code here to initialize your application before any files are opened
          end applicationWillFinishLaunching_
          on applicationShouldTerminate_(sender)
  -- Insert code here to do any housekeeping before your application quits
                    return current application's NSTerminateNow
          end applicationShouldTerminate_
    on displayButton_(sender)
        if (isShowing = 0) then
            ppw's orderFront_(sender)
            set isShowing to 1
        else
            ppw's orderOut_(sender)
            set isShowing to 0
        end
    end
end script
will toggle a second window from a button on the firsst window.
This is what the nib file looks like
ppw is attached to the panel.
This should get you started. Post back if you have more questions.
