The tower is, what will support the windmill and blades and needs to be as tall as possible. You should use strong but flexible materials. Plywood is a good choice. The tower should be 5 feet tall, at least.

What are the blades and how to do it?

The blades are, what will catch the wind and bring it inside the windmill. Normally, for the best energy gain and performance you should buy pre-made blades. Unfortunately that can be a bit expensive, but it's worth it. If you really cannot afford the pre-made blades, you should create your own blade, again using strong but flexible material (plywood is recommended). The blades should be in direct comparison with the tower, so if the tower has 5 feet tall, the blades should have three feet in length.

What is the gearbox and to finish my windmill?

The gearbox is very important. This piece is, what is going to permit that your windmill captures the energy. To finish your windmill you need to connect the blades with the windmill, and for that you can use a shaft, which is non-expensive and do the job.
