Hi! I read the description, it's good that it is clear on the requirements.
I've done my own projects on drawing on Swing components in the past, it should be fine.
We could take a look on what you have until now and add to it (or correct if needed).
After the code is done, I can assist with explaining all that's happening (seems like you want to learn this, not just complete the task:) )
About the price, my bid is the max in your set range (100AUD), that's because this low level Swing coding usually takes some time, especially if we want to have a clean, understandable code.
Let me know your thoughts on this.
Regards,
Radu
