Also if you are going to use tabs, I suggest you use DSTUDIO if you have already not done so.
It significantly reduces your time spent on making dialogs, as it is much easier to make them.
The only flaw is that it sometimes mixes up [the order] of your dialog ID's if you decide to make modifications to parts of the dialog after you have made everything - so plan everything out before you do anything!
It's a "visual" program so it's user-friendly and very easy to get accustomed to.
