I would like to hear your opinion about what is the best way to start building sweet looking UI. Right now it looks that there is three way to do it with Carbide.c++ UI Designer, with game API or with basic UI Components. I don't have any experience from UI Designer or game API but with UI components user interface building is hard and slowly at least if you want to make sweet looking UI.
So could someone give me some hints about how would it be to build sweet looking UI with UI Designer and Game API. At least using Game API I could get flexiber UI designing but it might take more time to finnish application UI. Also in the future 3D interfaces building could be done with Game API. Anything else that I should know?
