C++ - Image Drag and Drop into Google Documents / Gmail Editor

I'm looking for a C++ code and a sample .exe that would? implement an image Drag and Drop into Google Documents / Gmail Editor.? C++ application should work as a drop source and Gmail Mail Editor / Google Documents Editor running under Mozilla Firefox, Apple Safari, Google Chrome and possibly IE as a drop target. ## Deliverables UI should be as simple as possible, just enough to illustrate a working image drag and drop from C++ application to? Gmail Mail Editor/ Google Documents. Image drag&drop functionality exists built-in in Apple Safari and FireFox, I just need to replicate it in my application. For an example of the desired functionality using Safari or FireFox open a Gmail Mail Editor/ Google Documents editor in one window and any page with a picture in another. Now drag that picture into the page with editor and drop it into the mail letter / document edit area. Observe that picture is now part of the document / mail. I need similar functionality, but drop source should be my C++ application.
