GMWnv does not seem a "regular" struct.
if everything it contains is a pointer, you can perhaps treat
it as a number.

try this instead:
$GMW_NV_Create = new Win32::API("gm5s32",
"GMW_NV_Create", [], N);
$GMW_NV_SetValue = new Win32::API("gm5s32",
"GMW_NV_SetValue", [N, P, P], V);
$NewNV = $GMW_NV_Create->Call;
$GMW_NV_SetValue->>Call($NewNV, "Name", "John");
