Java – component centric NetBeans, GUI Builder (group layout)

I'm trying to design a JButton (an "OK" button), which looks good and must be horizontally centered in the included JFrame

I have taken several GUI builder tutorials（ http://netbeans.org/kb/docs/java/quickstart-gui.html ）, but the subject has not been found yet In other GUI builders (Delphi), this can be done by removing anchors from both edges

Solution

If you want to keep your component centered in the container, if the container is resized, you can choose several options, but I don't think grouplayout is one of them (if I'm wrong, please correct me) One way is to change the container layout to gridbaglayout, and then simply add JButton to it without any constraints
