digitalmars.D.dwt - XPCOM how to port?

In DWT-Linux the browser component is originally implemented using XPCOM.

XPCOM is C++ and Java uses a C++ wrapper lib to make it have JNI C 
functions.

Is there a way to port this, without the need to make a wrapper lib in 
D1.x?

Port the C++ to D?  :-(

On Windows we can use interfaces to comunicate with COM.
XPCOM is a short for cross plattform COM. Unfortunately i don't know the 
COM stuff very well. What are the requirements that interfaces can be used?

XPCOM and COM are almost the same. The base interface IUnknown in COM 
has the same interface as the base interface called nsISupports in 
XPCOM. Even the GUID (00000000-0000-0000-C000-000000000046) is the same.

see:
http://developer.mozilla.org/en/docs/nsISupports

"On Win32 systems, nsISupports is ABI-compatible with Microsoft COM's 
IUnknown interface."

So you should be able to use D's COM support for interfacing.
