It is the responsibility of the calling application to destroy the icon returned
from this function using the DestroyIcon function. 

But it is written for C. There is no GC. Do this apply to D also or the GC will
take care of it?

D knows nothing of Windows system objects.  As such, you have to delete 
them yourself.

Of course you can create a wrapper class with a destructor to do this work.

It depends on how you keep track of the icon. If you store it in an object then
you can use the object destructor to release the icon. Otherwise you have to
explicitly release the icon when you are done with it. See the section 
http://www.digitalmars.com/d/class.html#destructors
and
