I travelled as a child by train from Nice to Mons. Only one change of trains in Paris. If you could get to Avignon or Valence you would have no problems connecting. My french is not good enough to go browsing through french sites though. Maybe if you ask in France section how to get from Gap to either of the above towns you can fit the pieces of the jigsaw together?
Edit: According to the link posted below it looks like you can go Gap to Paris, change trains at Paris and get connecting train to Mons
