Mandar,
There is no point in making a programmer. Use ISP chips from atmel such at AT89S51, AT89S52, AT89S8252 these chips are easily available here in mumbai. All you need is a cable connecting your PC pritner port with ISP header on your working board. Chek this out a nice ISP cable schematic and software by M. Asim Khan.

There are several advantages of using ISP over parrallel programming. Best is you dont need to remove your micro every now and then while developing the firmware.
