Of course such is possible. For instance, my xwisp application can read 
a .hex file, alter a specific word, and then write the file back.

A simple in-circuit programmer would be a better idea: pickit2 would be 
a good candidate: it has both a GUI and a command line application.

Or use a bootloader...

>> UTILITY -16F877 -MYPROG.HEX

the actual command line for xwisp would be:
    xwisp target 16f877 go myprog.hex

Are you seriously using the 16F877? Consider at least the 877A, or 
better the 887.
