We are on the same situation man! I tried to negotiate with the new company regarding the same matter. But after all the deal, it all added up to one answer. "NO" you cannot bring them along with you. You have to go first, process medical,work visa, residence permit. Then after you yourself will request your company to sponsor for you or you yourself will aplly a family status visa for your wife & kids then after documents were approved. It will be the right time for you to bring them to Qatar. Or else if you know somebody who can help you, try to find a Qatari sponsor for a visit visa (or a travel agency) you can trust because this will cost you a lot too!
