A basic grasp of the language (both word wise and punctuation/grammar wise) and an idea for a story.

Anyone can be a writer. Just sometimes you get writer's block.

Three things are needed to be a good writer:

1) One needs to write

and

2) One needs an audience for one's writing

and

3) The audience needs to like the Pagsulat and/or find it useful (depending on the type of writing)

If one doesn't have all three, one cannot be a good writer. Note, though, that a writer's audience could be the writer herself. So, if one writes and that one is Pagsulat for herself, then that one is a good writer if that one likes the writing, no matter what anyone else thinks (because in this hypothesis, others are not the audience).
