What you are asking for is close to impossible without sincere effort.
Remember that since your program will have absolutely no connection with the target application which has rendered the word in the first place (your browser, notepad etc), you have to resort to different tactics than just a simple mouse hover event.
My suggestion is to try to capture the area under the mouse and then applying OCR.
I can't think of any other way this can be done.
