Yes, it is possible to use only horizontal and verticle boxes to do

and why do you feel so? I have nither used box layouts and sizers nor
gridbag layout. can you give me any reasons why I should not be using
box layouts both horizontal and vertical for my form with row of
textboxes and one row of buttons in the bottom?
is there some thing which this approach can't achieve which gridbag can do?
It depends. The StaticText/TextCtrl pairs is a classical problem.
Take a look at http://spinecho.ze.cx/ , LearnSizers5.zip.
This case is presented in different variants: a col sizer containing
row sizers, FlexGridSizer and GridBagSizers.
