Can you add a question mark to indicate questions?

Which part are you having trouble with?

Putting three JTextFields on screen is a simple matter,
try adding each to a JPanel with a GridLayout.  Then
you might also add a JButton to launch the program.

These are things described in the Java Tutorial.  
Layouts
<http://java.sun.com/docs/books/tutorial/uiswing/layout/using.html>
Events
<http://java.sun.com/docs/books/tutorial/uiswing/events/index.html>

Once the three text fields are filled in, and the button
acitvated, the code needs to call one of the Runtime.exec()
methods to gain a Process.  AFAIU, both input and output
streams of the Process need to be accounted for, for it to
work correctly.

Of course, launching a Java application by calling the main
is very kludgy.  If you can import the class, it is easier to
construct an instance of the class directly, setting parameters
as needed.

As far as doing it in NetBeans.  If you need to ask that
question, in the way you asked it, it indicates you should
not be working with a powerful IDE just yet.  All this can
be done in a simple source editor, and from the command
line.  Until you understand how to do that, an IDE will be
little use, and more of a hindrance, to you.

Please stop that.  It is known as multi-posting.
It is counterproductive, and very unpopular.
