Initially PCBs were designed manually by creating a photomask on a clear mylar sheet, usually at two or four times the true size. Starting from the schematic diagram the component pin pads were laid out on the mylar and then traces were routed to connect the pads. If you have many questions of PCB Design, please come here!

Is it able to put a trace rated for 120VAC 30A or so on a 2 layer pcb board that also has 5V dc controlling a microcontroller? What is the best way to do this for a double-sided?

What you said is possible, you just need to keep the trace at least 5mm away from anything else. But the bigger problem is that 30A is very large current and you will need some pretty wide traces, for 35um copper and 40K temp.

I have some questions for you: 1.Is one layer a ground plane? If so, does it cover most of the board area? 2.Is the 5V DC isolated from the AC?
