Getting started with blackberry 7 development? - blackberry

Question

Can someone please point me to the right direction on learning how to develop for blackberry 7?
Actually what i need is just to implement push notifications and open a web URL nothing more.
I see that there are different frameworks for this platform like webWorks etc etc.
I am a bit confused though.. I do not want to write Javascript or HTML or CSS.
I want to write native code that enables push and loads me an external URL which i already have.
Any tutorial on that or a bit of info would be great :)

Try this -
Client side code -
// Main Class-
class App extends UiApplication {
private static App theApp;
public App() {
pushScreen(new register());
}
public static void main(String[] args) {
if (args.length > 0 && args[0].equals("BB_push") ){
theApp = new App();
theApp.enterEventDispatcher();
}
else {
BackgroundApplication backApp=new BackgroundApplication();
backApp.setupBackgroundApplication();
backApp.enterEventDispatcher();
}
}
}
//Register Class-
public class register extends MainScreen{
public register(){
final ButtonField btn=new ButtonField("Register");
add(btn);
FieldChangeListener listener=new FieldChangeListener() {
public void fieldChanged(Field field, int context) {
if(field==btn){
registerBpas();
}
}};
btn.setChangeListener(listener);
}
}

System.out.println("\n\n\n\n\n\n msg RESPOSE CODE : " + response);
httpConnection.close();
