Sorry for not checking back sooner.

Here’s a function that returns more manageable data:

ObjC.import('CoreGraphics');

Ref.prototype.$ = function() {
	return ObjC.deepUnwrap(ObjC.castRefToObject(this));
}

Application.prototype.getWindowList = function() {
	let pids = Application('com.apple.systemevents')
	          .processes.whose({ 'bundleIdentifier':
			        this.id() }).unixId();

	return  $.CGWindowListCopyWindowInfo(
		    $.kCGWindowListExcludeDesktopElements,
		    $.kCGNullWindowID).$()
			 .filter(x => pids.indexOf(x.kCGWindowOwnerPID) + 1
			           && x.kCGWindowLayer     == 0
					   && x.kCGWindowStoreType == 1
					   && x.kCGWindowAlpha     == 1
			).map(x => [{ id     : x.kCGWindowNumber,
			              name   : x.kCGWindowName,
			              bounds : x.kCGWindowBounds  
					   }]);
}

To use, e.g. to get Terminal’s windows:

Application('Terminal').getWindowList();
