Well, if you have access to the source code of this program, you should
add an interface method that takes three parameters and then executes.
Modify the main method to read the command line arguments and then call
your new execution method.

OK. Make the action of the button be to read the text field values and
invoke the execution method. Also, you should name the button something
other than "OK", since that is generally used in dialogs to confirm or
acknowledge a message. Choose something meaningful like "whatever the
program does" or at least the prosaic "Run Program".

If you don't have access to the source of the program that you want to
run, then you may need to create a String array of the parameters and
call the main method of the program you need to run. But it would be
cleaner if you could follow the initial advice above.

If you want to get really fancy, you could put appropriate listeners on
the text fields and only enable the "ok" button when each field has
something in it.
