Direct output to screen

How can I directly output something to screen like OpenGL and DirectX?
Maybe a bitmap image or something...

Dev-C++, Win32, C++, WinXP SP2

edit
gamedev.net has alot of tuts.

I'll test SetPixel then. I will count it successful if it can display pixels on DirectX applications ;)

Edit1: Microsoft has no reference about SetPixel :(
Edit2: But my help file (win32.hlp) has :)

It isn't direct output, it is through Win32 API... now I'm gonna look through gamedev.net.
