If you're targeting modern versions of Windows (Windows 2000) and above, you can use the UpdateLayeredWindow function to display any bitmap (including one with an alpha channel, if so desired).

I blogged a four-part series on how to write a C++ Win32 app that does this. If you need to wait for exactly ten seconds to close the splash screen (instead of until the main window is ready), you would need to use Dan Cristoloveanu's suggested technique of a timer that calls DestroyWindow.
