Why would you use a 3D api or a game api to create a black borderless window with some text on it?
It can be done with pretty much every language that can talk to Win32.. C++/Win32 for sure (as I've said, just create a borderless maximized window and put text on it).. C++/MFC (yuk).
In C# this is done with zero code in 3 minutes.
You can bazinga the planet and do it in a Windows Store App in C++ using DX11.. but what's the point?
Maybe I am missing the point.
