XCode Noob

Anybody,

I am very new to xcode and coding in general, but with the newest SDK available for the iPhone I have found myself (like many others) interested in getting started. I downloaded the application called "SimpleDrillDown" from Apple's Developers Site. Below is an example of the code as I have revised it. The only thing I have been able to do is change the titles of buttons and windows.
================================

#import "SimpleDrillDownAppDelegate.h"
#import "MasterViewController.h"


@implementation SimpleDrillDownAppDelegate

@synthesize window;
@synthesize masterList;


- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Set up the window and content view
window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

// Set up the table view controller
MasterViewController *masterController = [[MasterViewController alloc] init];
masterController.appController = self;

// Create a navigation controller using the new controller
navigationController = [[UINavigationController alloc] initWithRootViewController:masterController];
[masterController release];

// Add the navigation controller's view to the window
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];


// Create an array containing some test data
masterList = [[NSMutableArray alloc] init];
NSMutableDictionary *dictionary;
NSMutableDictionary *characters;

characters = [[NSArray alloc] initWithObjects:@"A/F Ratio", @"Spark Timing", @"Intake Air Temperature", @"Engine Speed", @"Load", @"Boost Pressure", nil];
dictionary = [[NSMutableDictionary alloc] initWithObjectsAndKeys:@"Data Logging", @"title", characters, @"mainCharacters", nil];
[masterList addObject:dictionary];
[dictionary release];
[characters release];



}


- (void)dealloc {

[navigationController release];
[masterList release];
[window release];
[super dealloc];
}


@end

================================
My questions are...

1) After I touch "Data Logger" I want to be able to touch, for example, "Engine Speed" and a new window come across. How do I do this?

2) In this new window I want to be able to put a slider and a button, how do I do this?

3) Also, in this new window i want to be able to have an alert come up. how do I do this?

I have read a lot of the information, but it's not helping much. I was hoping I could get some good help here.

Thanks,
