There's no explicit reference to the Windows API in the GPL or LGPL,
but there's an important clause in both the GPLv2.0 and LGPL2.1:

"However, as a special exception, the source code distributed need not
include anything that is normally distributed (in either source or
binary form) with the major components (compiler, kernel, and so on)
of the operating system on which the executable runs, unless that
component itself accompanies the executable. "

In this case, the Windows API and DirectX would be considered
"normally distributed major components" of the operating system, and
thus be ok to use in a L/GPL licensed work.
