Technically there is not much difference between that and normal topics. e.g. "New topic" is New question and "Post Reply" is answer question.
Text like "New topic" is found in the language files and you can change it to whatever you want.
If you wanted to take it step further you could create a custom style to make it more Q&A like. Quick tip, if you wanted normal forum pages and separate Q&A section you can apply different styles to different sections of your forum.
“Results! Why, man, I have gotten a lot of results! I have found several thousand things that won’t work.”
