Can I convert Selenium Automation scripts to GUI program?

Yes. You can do that.

• Create a GUI using Java Swing

• In ActionListeners integrate your selenium code.

This project I created by using both Java Swing and Selenium. You can refer the code for your purpose.

How to integrate selenium with GUI?

• Let's say your automation scripts needs to be executed in multiple environments.

• Create UI by providing a drop-down or radio buttons to select environment.

• Provide a button called Execute to run your scripts. In ActionListner of Execute button you need to integrate your selenium code.

Sample code:

public class FrameSample extends JFrame {

    JPanel pane;
    JButton execute = new JButton("Execute");

    public FrameSample() {

        /* Properties of JPanel */
        pane = new JPanel(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();

        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.fill = GridBagConstraints.EAST;
        gbc.gridwidth = 2;
        gbc.insets = new Insets(0, 0, 0, 0);
        pane.add(execute, gbc);

        setName("Automation");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new BorderLayout());
        setSize(300, 300);
        setContentPane(pane);
        setResizable(false);
        setLocationRelativeTo(null);
        setVisible(true);
        setAlwaysOnTop(true);

        execute.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                try {
                    System.setProperty("webdriver.chrome.driver",
                            System.getProperty("user.dir") + "//Drivers//chromedriver.exe");
                    WebDriver driver = new ChromeDriver();
                    driver.manage().window().maximize();
                    driver.get("https://www.google.com");
                    Thread.sleep(5000);
                    // Do yuor stuff
                } catch (InterruptedException e1) {
                    e1.printStackTrace();
                }
            }
        });
    }

    public static void main(String[] args) {
        new FrameSample();
    }
}
