First of all ATMEGA 128 supports ISP. One can use the same ISP programmer used for ATMEGA 16/32 to burn a ATMEGA 128. In your target platform just take out the connections for SPI, (MISO, MOSI, SCK, and RESET) and connect those line to your ISP programmer. For schematic and PCB layout mail me : nibir.chakraborty@gmail.com. You can mention the details of the target board like what other things you want in the platform.
