WoW! At last i got it working, i replaced the 7407 n there was a short circuit on vero-board (due to careless soldering).
Now WinPicProg, IC-Prog & ProgPic can program & verify. I got it confirmed by programming in WinPicProg & then verifying it by IC-Prog.
But WinPic is giving verify error while programming, i think it's due to some interface problem.
By the way i got it working thanks 2 all of you, specially Nigel Goodwin.
I will certainly be using WinPicProg its gr8, thanks to Nigel
