IP address bar 107.108. ...

["kartikay malhotra" <kartikay malhotra gmail com>]

Dear All,

I am making an IP address bar in GTK. It would function as 123 . 445 . 521 . 444.

Now friends, I am facing 2 problems: 

1) How to ensure that only numbers are pressed. I don't want the user to enter alpha characters.
2) How to draw points in GTK, without using GNOME?

Many Thanks for your consideration.
