Newbie prob with functions...

["Nicolas Raitman" <new_world radar com ar>]

HI to all. I am completely new to GTK+ and that is why I am going to tell
you something:
PLEEEEEEAAAAAASSEEEEEEEE HEEEEEELLLLLPPPPP!!

Do u get it?
Well... I am learning all this, so I did... well... I am trying to do a
simple program. This program consists of an entry where the user will enter
his name and when he presses a button next to the entry I want a label
(which I already created) to get the text of the entry and display it there.
Quite simple isn't it, well I cannot do it, so please help. Here is the
code, I know is a lot, but please just tell me how to pass the arguments to
the function showname so that it can display the name in the GtkWidget
nombre.

I placed a comment in the showname functions, and other thing you mighy
think it is not ok just tell me and I will try to improve!

Thanks a lot!!
Nicolas
