I'm afraid that you cannot avoid doing the bit-banging youself.

The following projects that may serve
as an inspiration for you (atmega programs 
another atmega):

http://www.fourwalledcubicle.com/ButtLoad.php
http://www.arduino.cc/playground/Code/Programmer2

wrt to the schematics, sourceforge seem to drop your attachment,
I could place it on the web space and post a link to it. I'm still
not sure whether I should collect hardware descriptions like yours
for amforth. My current understanding is that amforth is pure
software on a very hardware centric level and I'm not a hardware guy at
all. ok, I find the hot end of a soldering iron, by pain ;=)
