To convert from an applet to an application, you need to understand how applets work and how applications work. Applets have methods that are called by a browser.
In an application, you will have to call those methods in your code.
Applications start execution at the main method.
The GUI should not require much change. The Applet class extends the Panel class. You can try having your code extend the JPanel class and have the main do the functions done by the browser: Create a frame and add the JPanel to the frame.
