Craigeedee,
Unfortunately, a number of people who arrive at OASC claim to have suffered a minor childhood wheezing problem that on inspection of their medical records turns out to be more than they are willing to admit (even to themselves). You have been given the best advice already in this thread in that there is no point in you attempting to conceal the fact. Before you will be seen at OASC your GP will be asked to forward your Medical Attendance Record (MAR). The OASC President of the Medical Board will read your MAR before you are invited for selection. The good news is that a genuine childhood (non-recurring) wheeze is not a bar to entry for pilot training. The rules pertaining to such medical conditions change from time to time and rather than decline your application, where possible, OASC will move mountains for candidates with a strong aptitude and good officer potential.
As of 2 Sep 07 you will not undergo a medical board until after selection (Part One is aptitude, interview and exercise phase/ Part 2 is medical and fitness test - Part 2 will take place some weeks after Part One). It is important that you do not attempt to conceal possible problems, as has been said before, to do so demonstrates a lack of integrity and post-selection OASC would not be happy to find that you had been economical with the truth.
Good luck
