The way I would do it is to create a UserControl, which contains a textbox and two buttons.
____________ __ __
| Text box ||B1||B2|
------------ -- --
The textbox has it's Anchor property set to Top, Left, and Right, and the buttons have Anchor Top and Right.
That way, the textbox always has the buttons in the same position - to the right of the textbox - regardless of what happens to the control as a whole.
Add a few properties to access the text, set the button captions, and a few events to signal that the buttons have been clicked, and you are done.
