Question

public void actionPerformed(ActionEvent e) {
String command = e.getActionCommand();
int number1 = Integer.parseInt(text1.getText().trim());
int number2 = Integer.parseInt(text2.getText().trim());
if (command.equalsIgnoreCase("Add"))
result.setText(Integer.toString(number1 + number2));
else if (command.equalsIgnoreCase("Sub"))
result.setText(Integer.toString(number1 - number2));
else
result.setText("Error in GUI");
}

Get rid of Boxes! As has already been said this ui begs for a GridBagLayout. Even if you just comment out setting the layout of the three panels the textfields' sizes are good.
