BlueJ help

Hi all

Im new to the forum and come in need of help.
ive got a programming assignment due but have no idea what to do
its to be done using the program BlueJ

below is the spec for the assignment, if anyone could help me out it would be greatly appreciated

To design and implement a program written in the Java Language to produce a system that will run successfully on the Java platform with four command buttons: up, down, left, right and a text window to enter ''n" pixels. These controls will operate a drawing tool composed of a moving GIF image of a pen in the applet window. When, say, the 'up' button is pushed, a line will be slowly drawn n pixels long. Four colour selector buttons additionally allow the drawing line colour to be changed. You will design your program using UML techniques and present full documentation including the Javadoc summary of your coded methods.

If you have no idea where to start, please have a look at this site here: Starting Writing a Program

After reviewing this site and giving it a go, please feel free to come on back if you have any specific problems or questions regarding this problem or your code.

We wish you the best of luck.
