In a complex window where there a multiple tabbed views like you have, think of the window controller as doing nothing more than managing the view controllers for each of the tabs, not the actual views in each tab. If your window controller is getting monolithic, it's time for a refactor.
For example:

(Ignoring the affects of having literal tabs in this window…) Each view up in the toolbar is a separate view controller, which is possibly composed of one or more child view controllers. In this particular screenshot, you're looking at four. The window controller has a piddly 600 lines of code in it which is merely for creating and swapping out views of the top level view controllers, etc. The real work is all done in a tree of view controllers.
There's a view controller responsible for doing nothing more than managing the table view displaying the query results table, and basically has this interface:
@interface ResultListViewController : NSViewController {
NSTableView * resultListTableView;
NSArrayController * resultListArrayController;
}
@property (readwrite, retain) NSArray * results;
@end
The view controller is the delegate and data source for the table view and manages a bunch of little things related to the table.
