There are two steps:

// Set WS_EX_LAYERED on this window 
SetWindowLong(hwnd, GWL_EXSTYLE,
        GetWindowLong(hwnd, GWL_EXSTYLE) | WS_EX_LAYERED);
// Make this window 70% alpha
SetLayeredWindowAttributes(hwnd, 0, (255 * 70) / 100, LWA_ALPHA);

Here is only one variable hwnd - handle of a window :)
