Help With Button Layout

[Kenneth Gomez]

Hello,

I am creating a simple GUI. However, I am having problems getting my
buttons to lay side by side. Do you know why my first two buttons are
spaced out so far.

Also, how do I get my menu, buttons and all to start at the top, left
hand corner, instead of the center of the canvas?

Basically, my layout is as follows :

Row 0 is the File menu
Row 1 is filled with buttons
Row 2 has two canvases, one start at column 0 and fills two columns
(i.e. column 0 and 1), the other starts in column 2 and fills 5
columns
Row 3 is an entry which fills 5 columns

Thanking you in advance.
