If I understood you correctly, all you should have to do is create an NSArray with one or more UINavigationController instances and assign it to the UITabBarController's viewControllers property.

You'd have to adjust it, but something like this might work:

NSMutableArray* controllers = [NSMutableArray arrayWithCapacity:4];

for (NSUInteger i = 0; i < 4; ++i)
{
    UIViewController* innerController = [[[UIViewController alloc] init] autorelease];
    UINavigationController* outerController = [[[UINavigationController alloc] initWithRootViewController:innerController] autorelease];
    [controllers addObject:outerController];
}

[tabBarController setViewControllers:controllers animated:YES];
