Is this end position winning?

Kingside pawns should be on light squares I believe to not obstruct your bishop or be targets for your opponent.

I see, well thanks.

In that case, since there is no point hurrying, I would prefer the moves h3 and f3 first. 
What do you think? 

Yeah, I like those two moves to start things off, for what it's worth.  Making sure there's no unpleasant tactic later to watch out for.

Ok.

I would actually like if I could take this position up with someone.

That is , I could play this position with somebody.

Thanks!

I like Bd2 just for the ultra cheap threat of Bc3 if he keeps the bishop and g pawn in the same place.

You could always practice it against a chess engine.

And scrottrf points out a good trick.  That kind of thing is important any time you want to force his bishop off a diagonal because he always wants to avoid the trade of bishops.

One idea to consider is 27 Ba3+.  Then after 27... Ke8 you both move your kings up to d3 and d5 like in the game, but now you can play Bf8 and push your queenside pawns easier.  Also I believe you will win the pawn ending after 27... Be7:  28 Bxe7+ Kxe7 29 Kf1 Kd6 30 Ke2 Kc5 31 Kd3 Kb4 32 Kc2 Ka3 33 Kb1, since you always have the tempo move Ka1.

Alas, I do not have a chess engine.

I managed to find some live opponenets who were willing to play Black here. Twice out of the three times I played, I won. However, on the last one, my opponent managed to stop my queenside pawn from marching.

Also, after the opening move, 9.Bd3, Black can win a pawn with Qxd4. In the game, intiutively I thought this was bad but I can't find a concrete variation to refute this

The posiion is a very easy win.

This statement disturbs me almost as much as hearing you agreed to a draw, when you were a pawn up.

Why no chess engine?  There are hundreds of free engines available to download.  They provide invaluable training tools for tournament players.

Yes, ideally, take black in this position against a strong engine, and play it over and over, and learn from its technique.

Could you recommend me some free engines?

Also, in the opening, was 9.Bd3!? ok? I think Black can get a pawn with ...Qxd4. It seems pretty hard to refute this variation. True, Black has moved his Queen too many times in the opening and it seems that he shouldn't be able to grab the pawn on d4 without paying for it ...

Opposite color bishops are where the real draws happen.  And rook endgames.

chess102410  The win is relatively easy. My suggestion is to find some player Class A or better and ask him to play he position out with you for a few times.  You will learn very quickly how easy it is to win such a position.

Then after that when similar positions come up--you will know what to do and gain a lot of chess knowledge.

One more point. When playing a game and your opponent offers you a draw--try to figure out why he thinks he is losing.

"The winning plan here is...to create a passed pawn and queen it."

He felt it necessary to state that?

Yeah sometimes I prefer to rook it though http://www.chess.com/echess/game?id=78835474

Could have built an army of knights.

Averbakh's position is much easier since the white king gets to c4. In the OP's position I don't think the win is easy, though. Here is how I would attack it.
