Let's see if I can seduce you to the dark side :-).
The BASCOM compiler, which works on 8051 and AVR,  has functions for 
Flash interface built in. Also useful things like AT keyboard, 1 wire, 
multiple UARTS, SPI on any pins, LCD interface, 1 Wire, IIC in 
software and far more.

It's free up to 4K code which is probably enough for the Flash code 
(I've never tried it).

A programmer can be built for a dollar or so of parts.

The Studio software (equivalent to PIC MPLAB) is also free.

Tempted?
