First off, read the link in my signature on asking smart questions. For example, many people here don't speak English as a first language, so abbreviations like "tnx" and "u" can be confusing, plus it just makes you look lazy. Also, it's pretty hard to answer "how do I do this" type questions. What have you tried? What worked, what didn't work? How didn't it work? Be specific, post an SSCCE
that demonstrates what you've tried, and we'll go from there.
But just a word of advice: write the game logic before you worry about the GUI. Get everything working on the command line first, before you write a single line of Swing code.
And once you're ready to write the GUI, give this a careful read-through: Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)
I think what you'll eventually want to do is extend JPanel and override paintComponent() to draw everything. Read also: Painting in AWT and Swing
