I did the file association by hand myself, but here goes. WARNING: 
UNTESTED CODE. I picked this together from MSDN. I have no compiler on 
windows. The CMD and APPPATH #defines would obviously need to be 
runtime-determined strings.

LONG res;
HKEY hk = NULL;
DWORD disposition;

#define EXTENSION ".xwar"
#define APPTYPE "xwar"
#define MIMETYPE "application/x-xwar"
#define DEFAULT ""
#define APPNAME "XWT Archive"
#define APPPATH "c:\\path\\to\\xwt.exe"
#define CMD "\"" APPPATH "\" \"%1\""
