Thread: Need help in creating new simple java GUI with rectangle, square, moving object, etc.

Hello, I'm new to this forum and completely new to java programming. I'm thinking of creating java GUI with the use of swing. But I'm completely lost. What I'm trying to do is to create a football field GUI. It goes like this:

First, I want to create filled green color rectangle which will be used as the playing field which 800 pixels long by 400 pixels wide. A white rectangle outline will be used as boundary. The goal will be 200 pixels long. The ball will be 50 pixels wide. Then, a rectangle with red color will be used to represent players on the field and oval (with black color) will be used to represent ball. Next, I want to create a long rectangle with blue color which will be use as game timer and put it above the field.

Here how it look like:

I have view some tutorials about Animate Circles, Bouncing Balls, Moving and Scaling, Re size Rectangle, Show Clock Timer, etc. But I'm clueless. So I really hope that this forum will not disappoint me.

Start by write a class that extends JFrame and adding a JPanel to it in which you will do the drawing.
Override the JPanel's paintComponent method and add code to it to do the drawing.
Do a simple drawing at first and add to it as you go along.

Thanks for the advice guys.. Right now I'm using Eclipse Helios with WindowBuilder. I've done the drawing but still struggling on the next step..
