If not Which is the best software ? easy to use ?

Some tutorial links plz....

No. The Arduino has to have some code on it.

If not Which is the best software ? easy to use ?

There is no off-the-shelf, pre-written, control-my-Arduino software. There are plenty of products that let you build a GUI and talk to an Arduino. Some are easy. Some are less so. A lot depends on what programming languages you know. None expect that you don't know any programming.

My purpose: controlling stepper

Way too vague. What, EXACTLY, do you want the stepper to do? What, EXACTLY, do you expect to have the GUI send the Arduino? Number of steps? Time to step? Phases of the moon?

More info:
I am doing a controller for CNC milling machine..using arduino and driver for the three motors (3 axis).

I want to build a GUI on my own...i know C++
How do i do that ? What code do i upload ?

Do you mean that you want a GUI that runs on an Arduino (perhaps on an LCD display?) without any connection to a PC?

Or do you mean a GUI interface on a PC that sends commands to the Arduino?
