That's perfectly acceptable, as long is the question is about an actual problem or can have a definitive fact-based answer and is on-topic, you can ask it. If you bump into a problem that you think might be tricky for others, feel free to write about it here. I have done so successfully in the past. Of course, people are free to downvote if they think the question is lame (i.e. lacking research effort).
As Can I answer my own question? says, you'll need to wait two days before you can accept your answer. You also won't get the +15 rep for the accepted status or the +2 for the accepting, though upvotes will still count for +10.
