boxxy | Layout manager for web apps

I'm working on java game and when i add JPanel with JLabel buttons to JFrame, buttons don't show up until i hover over them. I tried removing mouselistener, but it just makes buttons invisible even if i hover over them. I also tried: validate(),revalidate(), changing order of adding components to Jframe.

Game.java:

I have this code that defines a drawScene0 function which is supposed to interact with the user, responding to mouse clicks and keyboard but it doesn't seem to do it it just draws and when i try click or type, it does't work. I tried debugging the events loop inside the drawscene function as well as the main while loop, what i found was that the events loop inside the main while loop seemed way way quicker and responded perfectly, on the other hand he event loop inside the drawscene function was much slower in comparison and sometimes not even responding to clicks one in like ten clicks was being printed and even that one click was not doing what its supposed to do i'm really confused. Please help. Thank you! I posted the full code for maximum understanding please don't mind the messed up code. Here is the code:
