The only way I can think of to do this would be to create a Word document and embed the .gif image into it. That can be done programmatically, but it's kind of complicated in C++ (probably easier in, say, JavaScript or VBS).
Please provide some more details.

To add to DanRollins, you have to have MS Word installed on the computer where this is to be done (programmatically). There is no other reliable way to do it without having MS Word installed. The reason is that the program will use the Word components to do the action.

Any particular reason it must be a word doc file?  
There are a number of 'document' formats (eg. rtf, HTML) where your task would be a lot easier.

Something like this should be OK for html


<html>
    <head>
    </head>
    <body>
        <IMG height="122" width="462" src="abc.gif">
    </body>
</html>

I can only show you fragments of code (not a fully working example) that uses Word97 (i.e. the interface version 8). The interface is also supported by the newer versions; however, the #import commands require the presence of the old dll's. You should be able to do the same with newer dll's but I have no experience with the newer interfaces. I also use WTL instead of MFC, but that should not make a big difference.

This is my really old code that was simplified (the image was originally generated) that was used for learning the export to Word. I did not compile it now. But you should get the idea. The

#include "mso97.tlh"
#include "vbeext1.tlh"
#include "msword8.tlh"

included header files (and the not-shown *.tli) are the result of #import of the related files.


#include <atlbase.h>
 
#include "mso97.tlh"
#include "vbeext1.tlh"
#include "msword8.tlh"
 
#include <cassert>

#include <iostream>
#include <sstream>
#include <string>
 
using namespace std;
 
CComModule _Module;
 
float mm100ToPt(int mm)
{
    // Convert hundreds of mm (integer) to pt (float), because that 
    // unit and type is required for document properties.
    //
    return static_cast<float>(mm * 720.0 / 25400.0); 
}
 
 
/*! \brief Predicate of the file existence.

bool isfile(const std::string & filename)
{
    WIN32_FIND_DATA FindFileData;
    HANDLE Handle;
 
    // Search for the file.
    //
    Handle = FindFirstFile(filename.c_str(), &FindFileData);
 
    // Not found => false.
    //
    if (Handle == INVALID_HANDLE_VALUE)
