basic question from GUI beginner

Till now I never Tried GUI on my machine,except reading thhrough different tutorials in the net.
TOday I tried to create a frame and just onebutton in it.
When i compile it is warning me to recompile with
and I did the same.
Here is the code for my simple program
public class createButton
public static void main(
Frame f = new Frame("First Frame");
Button b = new Button();
It is compiling succesfully,but when I run the newly created frame is not visible anywhere.
though it is giving 2 warnings I run the program.
Is this the reason for my newly created frame invisibility?
One more thing that is confusing me is, in variuos tutorials in some code, the class is extending
and some are using JFRAME from javax.swing class.
I am a beginner for GUI programming as I never tried before.
I just want to create some compenents in a container.
I want to create containers in my main()only and want to add components to it.
Is that not possible without extending Appplet claass or Swing classes?
If you find this silly,please spare me as a beginner in GUI.
Thanks in advance.

Well - for a start, your call to System.exit(0) is exiting the application, and so, not surprisingly, closing the frame also.
I'm surprised you've managed to go 57 posts and a year without finding the [code] tags...

. . . and show() has been deprecated for ages. That is probably why it is suggesting you use Xlint.
Another reason for not seeing much is that you have not given the frame a size.

There ought to be instructions for setting up a GUI in any
book except the very smallest, and here in the
