You can do it by subclassing NSWindow's View.

Create new window view's class (For example with title WindowViewSubclass).

Then .h file should look like this:

#import <Cocoa/Cocoa.h>

@interface WindowViewSubclass : NSView {

}

@end

and .m file:

#import "WindowViewSubclass.h"

@implementation WindowViewSubclass

- (void)drawRect:(NSRect)dirtyRect
{
    NSGradient *gradient = [[NSGradient alloc] initWithStartingColor:[NSColor orangeColor] endingColor:[NSColor lightGrayColor]];
    NSRect windowFrame = [self frame];
    [gradient drawInRect:windowFrame angle:90];
}

@end

Now select window's view and go to Identity Inspectory -> Custom Class -> and select class like this:
