If you really want to learn DirectX11 then the Rastertek tutorials are excellent... you will have to write quite a bit of code (there are lots of different things to set up when opening up a window from scratch), but it's reasonably well documented.
http://www.directxtutorial.com/LessonList.aspx?listid=11 has a lot more documentation if that helps, but you'll want to head back to Rastertek for more interesting effects.
