Do I think you'll be able to learn it? Who the ... are you? I mean seriously dude - how can we answer if YOU will be able to learn it over someone else?
You learned Flash? Ok - there's hope. Start with the Visual Studio Express compiler - and try to figure out how the compiler works etc. Try some C+ tut's here: [href]www.cplusplus.com[/href] Learn the boring junk first - otherwise you'll get stuck every other command that does some C++ jibberish.
Play a little with the "Trial" Dark Basic Classic Download - just to get a tiny taste of how the 3d more or less works.... Just make object cube... try moving cube around, camera around, just play and experiment.
Get back into DarkGDK - make sure you can compile a wizard - the wizard demo has a little thing with oval orbs rotating - if you can compile and get that to run - you're at a good starting point.
Give it a whirl. In the future try to do better for Opening Subjects - and TRY to hit us with ALL successes and questions that are a little more specific.
This is a great community only when all the members are reasonable.
(I'm not always reasonable either BTW) Good Luck
