Imgui: Single window

[mnemode2]

I want to use imgui for my simple windows application, I want one window with several controls (bottons, etc)
Is this possible to create such window with imgui?
I don't want one big window with imgui subwindows but one imgui window with controls

NOT like this:

I want to build desktop app

Just create an OS window that doesn't have OS decorations, then create an imgui window that fills the OS window using SetNextWindowPos(ImVec2(0,0));SetNextWindowSize(io.DisplaySize);`

" OS window that doesn't have OS decorations"
How can I do that on Windows?
via CreateWindow?

That's not a question related to Dear ImGui. Look up for WS_POPUP WS_EX_TOOLWINDOW flag in Win32 api.
