Solution 1:

I don't think you can create a button on the Home Screen on-the-fly by coding. In my book, the only way to get a button on the Home Screen is if the user adds it as a widget.

Solution 2:

If you are using xml layout for it add the button widget you needed and set it's visibility by android:visibility="gone",when you clicked the first button to activate the button to display,make it to visible by getting the id of the corresponding button for eg: btn2.setVisibility(View.VISIBLE);
