No, ASIC's are created in a chip fab.

Alot of FPGAs are 3.3v only, it's easier to hook up if it uses 5v. 
However I believe there are ways round that.

Not necessarily, 110v and 240v appliances aren't more forgiving. They 
are just designed for different voltages. If you have a 3.3v ASIC then 
it will be no different to a 3.3v FPGA

Some people use the HDL they use to test an FPGA to create an ASIC with, 
it's not necessarily a simple process to go from one to the other. 
However you need to be making many thousands of them to cover the cost 
of making an ASIC.

I would definitely start with a simple project.
