Tic-Tac-Toe in SWT

How do I create the buttons with an array? I am going to do a Tic-Tac-Toe game in SWT. I guess this way is wrong?:

Code :

import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;
import org.eclipse.swt.events.*;
import org.eclipse.swt.graphics.*;
import org.eclipse.swt.*;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.events.SelectionListener;
import org.eclipse.swt.widgets.*;
 
 
public class Application {
 
	public static void main(String[] args) {
	    Display display = new Display();
	    Shell shell = new Shell(display);
	    shell.setText("Tic-Tac-Toe");
 
		// creates the gridlayout
		GridLayout gridLayout = new GridLayout();
		gridLayout.numColumns = 3;
		gridLayout.marginWidth = 50;
		gridLayout.marginHeight = 50;
		gridLayout.horizontalSpacing = 10;
		gridLayout.verticalSpacing = 10;
		gridLayout.makeColumnsEqualWidth = true;
		shell.setLayout(gridLayout);
 
		// creates the buttons
		Button[][] button = new Button[3][3];
 
shell.pack();
		shell.open();
		shell.setSize(700, 700);
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch())
				display.sleep();
		}
		display.dispose();
	}
}
