What do you need to learn OpenGL? Do you need to learn C/C++ first? I have experience with C but none with C++.

I would suggest using c++ due to it having an object oriented side, but the opengl is cross platform
http://www.opengl.org/resources/bindings/

You can use mostly C with very little C++.
I would suggest looking at nehe.gamedev.net for some tutorials to help out.

I am not familiar with OCamlgraph library? I am not able to find any good documentation for the same? I am not able to run any small examples also. I want to find all cycles in graph for that I am using it.
Anyone aware of any documentation? Or a set of examples for the same?
There is the paper on ocamlgraph:

And aside from the examples on the ocamlgraph homepage, there is a more compact code example here:

I'm looking for an OpenGL tutorial. Could you suggest something? I want to create some object, move them and give some light.
This Lighthouse3D lighting tutorial is excellent and not really bound to OpenGL.

I am starting to do some development in C++ which includes the use of COM interfaces in Windows. I have to make a decision to learn or not to learn the COM technology. So, I want to ask if the COM programming is still widely used or is it rather outdated? Is it still a good idea to invest ones time into learning COM?

Anyone have any links or resource regarding writing a proper C++ FastCGI application? (on top of Apache using mod_fastcgi or mod_fcgid).
I suggest you fastcgi++, which is an alternative to the FDK.
It is much more easy to use and is in a C++ way.
The obvious one would be the FastCGI Development Kit (for C/C++).

I'm looking for a QR-Code library for C/C++, not Java or .Net please. Anyone knows of one?
Note: There was a similar question a while back however but it didn't get
answered properly.
How is this one?

The zxing library is primarily Java, but, includes a port of the QR Code detector and decoder to C++.
