Well, if you just added an answer, that will bump it back to the front page.
There's no real way to add a question/answer to your profile, unless you link it in your About Me section where you can put whatever text you like (so you could include a link there if you wanted), although that doesn't guarantee more visibility (as people have to visit your profile specifically to see it). Unfortunately, there is no other way to add questions to your profile in the way you like (although your profile does list all of your questions and answers anyhow, you can't highlight specific ones short of using your About Me box.)
You could also add a bounty to the question, although since you answered the question, you would have to have the bounty set at a minimum of 100 reputation, which you don't have yet (and if you set a bounty, you lose that amount of rep until you earn it again through up votes etc). One of the bounty reasons is to draw more attention to a question, which would then also draw attention to your answer.
