Assuming the NOPPP is working with the 16F84s, all you need to program 16F826s is the updated software. This can be found at: http://www.geocities.com/jpadfield13/noppp3.html With an adaptor PCB to get up to 40 pins, you can use this software to program 16F87X chips aswell. I wrote some software to do include the 16F877s, I believe James' latest software includes these aswell....
