There are an abundance of choices to be made when we want to develop Windows programs. There are so many choices that just figuring out what we need to learn requires learning very much.
If you want to learn how to program Windows in a manner that you are likely to get help then you should use a .Net language, either C# or VB .Net. C# is the better choice. Microsoft does not support C++ very well for use with .Net, primarily because
the design of .Net makes it difficult to use in C++.
For .Net you can choose to learn Windows Forms or WPF or UWP. Windows Forms is closer to the original way of programming Windows but Microsoft encourages us to not use it. UWP applications can, by definition, be used in all versions of Windows but they
have less capability to interact with other programs.
As RLWA32 says, the details of how to create a frameless window depend on what you choose to write the program. Understanding the details of how to do that also require some familiarity with Windows; if you don't understand then you might end up with a window
that you cannot close (normally) or that you can't do other things with such as minimize or move and other things.
Probably you will benefit from a good book but I don't know what to suggest. You might decide after learning something that it is not what you want but at least then you will have a better understanding of what you want.
