If you have never programmed in any language and want to get something easily with GUI so you don't get tired, VB is the answer. But VB is "dead", so don't stay a lot with it. Use it to learn how to work with bucles and progam flow management. Then, switch to something better.
Perl | Python | PHP are good to begin too, but GUI is harder with them.
To end with, C is the best I kwnow. Also, it is the hardest of them. But if you learn C, a lot of the rest will be really easy to learn.
If this is useful to you, I started with VB and then switched to C. After learning C, Perl and PHP were easy as fuck.
