  /** Called when the activity is first created. */
 @Override
   public void onCreate(Bundle savedInstanceState) 
   {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    int size=10;
    ScrollView sv = new ScrollView(this);
    LinearLayout ll = new LinearLayout(this);
    ll.setOrientation(LinearLayout.VERTICAL);
    sv.addView(ll);

    TextView tv = new TextView(this);
    tv.setText("Dynamic layouts ftw!");
    ll.addView(tv);

Look at this: Android: How to programmatically add button to view

As far as accessing the Button Id. It probably wont have one unless you set it.

read the Android docs: http://developer.android.com/reference/android/widget/Button.html then do a search (CTRL+F) for setId – slayton Sep 16 '11 at 18:30
