I would like to know if there is an already samples of doing data flow graphs using QT graphics API.
I would like to see some samples to get started with.

Qt comes with various examples that might help you get started.
The following two examples come to mind:
The Diagram Scene Example
Elastic Nodes Example
Have a look at those for some inspiration.
Qt-based, but a separate project which is possibly more along the lines of what you're looking for is NUKEEngine's Qt Node Editor.

I am writing a program, and I thought that it would be better with images (I am creating console application). So I want to know if it's possible? And if it is how can I do it? Thanks.
You can do it by ASCII art, There are many open source libraries which convert image to ASCIIs, such as libcaca.
And if you want use colored images, you can use rlutil.
Consoles are designed to display characters only. With some very crude exceptions it is not possible to display images unless you open another window.

I'm working on my final year project on ocr in opencv,i have done segmentation of the image and feature extraction,now i have to train to make it recognize the alphabet ,give me an idea of how to do that
I don't know what you have done until now and what feature set you are using. Anyway below links will be a good start.
1) Basic OCR in OpenCV - It uses k-Nearest Neighbours
2) Also try this : Simple Digit Recognition OCR in OpenCV-Python
3) OpenCV samples come with an letter-recongnition sample. Have a look at that!!
Finally, work yourself a lot on your project. Google for your doubts. If you don't find any way,
come here, tell what you have done, and now what is stopping you.

I want to write an event listener in C++ for MS Excel (2007/2010), and I am looking for resources that can get me started, preferably a working code sample.
Microsoft Support has a HOWTO called "Handle Events for Excel by Using Visual C++ .NET". The example code there is fairly long, so I don't want to paste any of it here. Ask new questions if you find any of it confusing.

OpenGL only deals with drawing stuff. It gives you a canvas and some primitive drawing tools. Nothing more. Anything beyond that is the task of the user interface system provided by the OS.
Maybe you're using GLUT and are mislead by its name. GLUT is not part of OpenGL; it's a rudimentary framework aimed at developing simple OpenGL example programs, but that's about it.

I'm looking to get hold of an example of a simple mp3 player that'll work without the need of flash, Just need to say play/stop and that's it.
Any help would be great : )
Because you mentioned flash I think you search a player for web pages, am I right?
If yes, then you could take a look at jsmad. It's a decoder (aka player) written in JavaScript (but therefore needs a decent browser).
Or you could use the audio-Tag of HTML5.
