So My problem is that the applet lunches with nothing in it as soon as i hover the mouse
on top of the buttons it displays them and works perfectly afterwards. I think there might be something wrong with paint but i am not sure. I tried several changes but noting seems to work.
Any help will be much appreciated.

I took sometime to modify the code of yours and I removed the paint() method and its working, now the screen display’s without any freezing and all the components are displayed. Here’s one important information for you which i found regarding paint() method when you extend JApplet.
Note: Move the logic which you had in your paint() method according to your design.
Below is the modified code, Hope it helps!!!
