Load program into PIC18F without using PICKit or ICSP

I am currently learning about using PIC18F4550 for my project. Is there any way that I can load the program into the PIC without using ICSP or PICKit? At the first time of using the PIC, can we use USB to load the program into the PIC?

You can try the simple PIC programmer found on this page. It works with PICpgm, which is freeware. I've used this software before and it should work great with the 4550.

I had this question myself,

To program a PIC, many devices can be used. Microchips website gives couple of options . However, The PICKit can program and also do hardware debugging for PIC controllers. There is ICD3 which gives access to more in-depth analysis. There are many more third-party programmers for the PIC controller.

One of these programmers are needed for programming a PIC for the first time. your PIC can be initially programmed with bootloader code. Once you load bootloader you no longer need any programmer. You can send your Hex files over USB or UART and PIC will program itself with this new hex Code. ezbl from microchip has way to do it with USB but it only works with PIC24/dsPIC33

Microchip has very good documentation on bootloader AN851.
