How can I draw text correctly in a function?

[Jung-Wuk Hong <jwhong MIT EDU>]

Hi.
Thank you who answered my previous question.
Now I don't have waring (Drawable !=0), but still cannot see the letter
which I
want to draw.
According to advice, I added gtk_widget_realize().

What's wrong in this code. (I can see only button, not text)

Thank you in advance.
