Check out http://opengl.freehosting.net/glfw

You can use glfwGetMousePos(&x,&y), and then use the x-values for “turning” information and the y-values for motion information.

The better approach is usually the famous “mouse-look” method: mouse x controls turning, mouse y controls “look up/down”, and then use the keyboard for movement (forward/back and left/right (“strafe”)).

In your WindowProc you can also check for the WM_MOUSEMOVE message that gets called when the mouse moves. The LOWORD of lParam is the x and the HIWORD of lParam is the y coord of the mouse.

You can also use

POINT mouse;
GetCursorPos( &mouse );

to get the mouse position.
