How to efficiently align widgets to the right of frame and keep it there upon window resizing?

[BhagyaJyoti22006]

WHAT I WANT TO ACHIEVE:
I have a frame and two button in the frame. The frame is sticky="ew" and expands as the window expands in east-west direction. But the buttons stay where they were. I want them to move towards the right of the screen as the screen resizes.

WHAT I DID INEFFICIENTLY:
In the meantime, i added an extra column in the frame on the left. And added a dummy frame in this column. Set its sticky="ew". Such that when the window resizes, the dummy frame resizes itself. And the buttons are moved towards the right.

Please suggest me a better way to achieve this. There must be something simpler which I am currently missng out.
