Add translation on vocabulary track: record while listen?

[samz]

Hello,
I have a track (Voc.MP3) of Japanese vocabulary words (Minna no Nihongo), like:
Word1, pause, word2, pause, ... (= total 3 minutes).

I would like to add the word's translation in this track, to get a new track: VocPlusTrans.MP3, like:
Word1, translation1, shorterPause, ... (= total 3 minutes).

To be synchronized, I would like to use this method:
- Create a new empty track (Translation.MP3, 3min.)
- Listen Voc.MP3 while record translation in track Translation.MP3 (to be synchronize).
- Merge Voc.MP3 and Translation.MP3 (not concatenation), to get the result VocPlusTrans.MP3 (3 min.).

1. Is this method realist and doable?
2. Which audio editor software can do this: record trackA while listen trackB (or listen trackA)?
3. Do you know other forum focused on audio editing?

Thank an regards.

SAME QUESTION IN OTHER WORDS
I have Voc.MP3, I would record Translation.MP3 (while listening Voc.MP3, to be synchronized).
Then, I would get VocPlusTrans.MP3 merging the 2 tracks above.
(_ = silent/pause)

Word1_________________Word2_________________Word3_ _______________ ... (Voc.MP3, 3 min)
______Translation1__________Translation2__________ Translation3___ ... (Translation.MP3, 3 min)

Word1_Translation1____Word2_Translation2____Word3_ Translation3___ ... (VocPlusTrans.MP3, 3 min)

A. Which audio editor software can do this?
- record while listening.
- merge a track over another one (as this diagram above).

B. How to check if a sound card is duplex-capable (to record while listening)?

CONFIG:
- Vista Ultimate SP1 FRENCH
- Dell INSPIRON 6000. Intel Centrino 1.6 GHz, SigmaTel C-Major Audio, (micro to buy).
