What you want to do is little complex

On Arduinos, they use a usb to serial bridge ic like the FTL232, there is no built in burner. The IDE compiles and loads the hex via the usb to FTL232 to AVR UART. Arduinos have a bootloader.

So to duplicate this for a pic you will need a bootlader file. Then you will need some kind pc script program that takes the hex file from a folder and sends it out the usb port. Most pic pcbs use ICSP port and an external programmer.

Microchip app note describes the process. It's old from 2002 so not sure what resources are still available?
