I'm going to contradict myself.....
Despite the fact that I said earlier Tri-X and D-76 is easier and forgiving therefore my recommendation, the difference between films and developers aren't as big as they are often made out to be. With possibly exception of Lucky brand (which I have no personal experience but have heard some dubious reputations), they are all capable of producing fine results. This is especially true when one is not going to try to control one aspect of the combination or another.
If you are in a country/environment where wide variety of choices aren't readily available to you, just pick one that is easily and inexpensively available and play with it to your heart's content. With practice, you could do a fine job with any quality film.
