You need to create an instance of your Application class and add it to a JFrame:

mport java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class Application extends JPanel{

    public static void main(String[] args) {

        JFrame frame = new JFrame("FrogVibes");
        JPanel application = new Application();
        frame.add(application);
    }

    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.drawRect(0,700,400,100);
        g.drawRect(0, 600,100,150);
    }
}

Also, the method must be named paintComponent(), not Graphics(). Now Swing will call paintComponent() when it draws the window.
