Stretching and aligning components to form size

I have a form with a Panel, a Memo, and three Buttons. The Panel has
Align set to alTop, the Memo is just below it, exactly below it (as
close as I could get) and then the buttons are just below the Memo.
Problem is, I want to some how have the Memo snapped/aligned to the
left and right edges of the form, and the top edge too (directly below
the Panel).

So if I resize the whole form, there is the Panel across the top width
of the screen, then the Memo across the width of the screen below, then
the buttons below the Memo. So far, only the Panel is displayed in this
way. The Memo seems to only have a Align alClient - but this also
aligns the bottom of the Memo to the Buttom of the form, but I want the
buttom of the memo to align about 3 inches up from the bottom of the
form (other three sides align alClient).

Any ideas?
