Application to find my games (wishlist) on SteamGift

I want to make an application in which we can do a search on steamgift games we want. To do this, i will need an user and a password for every people, like a perfil. Actually I'm just trying to find games that I really want to play, but my wishlist is like 50 games, so it is very slow search all game search in SteamGift.

I also want to add an option to search for games with fewer entries thus to increase our chances of winning (this is general for all games available in steam gift, so i wont need your user).

So, tell me, what do you thing about do this. i will do it for me, because it saves me time. I can give you a copy if you are interesting or post here (for free obviously).

Other question I have is if steamgift would block me or something like that for doiing something like that.
THANKS
