it will get you started... but you can never lean back because you'll never know enough... it will get you started for about 5 minutes. you wont achieve much with that knowledge but others knew less when they started. just dont expect to make something great and impressive for the first weeks :)
you didnt tell us what you want to do with your knowledge. if its a windows thing then you'll have to learn all the windows stuff at first (because you said you already know console stuff). then use directx or opengl to display something nice on the screen the rest is nearly the same as in dos.

happy coding

if you know dos then all you need to know is how to make a window, how to set up dx or ogl and then draw stuff on the screen. behind the grafics everything looks just like dos.
this was what i have read to start win programming
after you have a window you can dig up some tutorials about directx or opengl. there are many good available.

i dont exactly understand what you want to do... you said you want to write a console game first but not text based...? maybe i understood something wrong... its 7am and i'm still awake...
