First, go to the microsoft website and download a language of your choice.
Either VB or C#.
Learn .Net as that is the current standard, and the one that is the most employable at the moment.
These come with a course of lessons, so follow them and pick up the basics.
Then come back to this site when you run into problems, which you will, and you will find people here only too willing to help.
Best of luck, and enjoy, there is much to learn and it is an interesting journey.
