Tiling with Trominoes Java

I need a simple, not professional, code to solve the tiling and trominoes problem with GUI in Java. The user must have the ability to choose a size between 2x2 up until 32x32 or 64x64. Also the user must have the ability to choose, by mouse, which square is being selected as a defective square for the problem and the solution of the other squares should be colorful. I need it to be as simple as possible. I need it by Friday 5:00pm EDT
