      import java.awt.Color;
      import java.awt.Frame;
      import java.awt.Label;
      import static java.awt.EventQueue.invokeAndWait;

      public class AWT {
          public static void main(String[] args) throws Exception {
              invokeAndWait(() -> {
                  Frame frame = new Frame();
                  frame.add(new Label("TEST"));
                  frame.setUndecorated(true);
                  frame.setBackground(new Color(0f, 1f, 0f, 0.5f));
                  frame.setBounds(200, 200, 200, 200);
                  frame.setVisible(true);
              });
          }
