Are we able to include/insert Computer graphics function in qt creator? I mean are we able to include all functions of Computer graphics even those that are not predefined in qt creator? Suppose if i want to insert Square shape in a container frame so what will be code for that?

You can use OpenGL with Qt widgets. Also, take a look at QPainEvent and QPainter class.

I am new to OpenGL. Can you tell little bit about OpenGL? and Please provide some code to draw square.

First of all, read a book. If you are new to OpenGL it is impossible to explain it in few forum posts. I recommend OpenGL Programming Guide (the "Red Book"), but you may find many others. Just pick one and read it.

Follow these tutorials to get a clue in openGL: http://ogldev.atspace.co.uk/
after reviewing the first few lessons, google for coloring and cube examples under QT.

If you are looking for something as simple as drawing squares, definitely have a look at QPainter as stampede suggested.
It's not hardware accelerated, but still good enough to draw all widgets and in some quite complex styles.
