no, coordinates was my real problem along with sizing and related issues.
reading your email gives me some comfort now.

ok but I will like to leave some wide gap between my 4 rows with edit
fields and the line of buttons, will I be able to do that?
and if the box sizer is vertical, how can I put a custom grid of
lebel-text pares?

the layout will be not actually 2 colums but 4 columns.  a lable-text
pare with very little space between the static text and the textctrl
then some significant gap before the other pare.  means column 1,2
with little or no space and then some significant space and then
column 3 and 4.  then some line gap for the next row and follow the
same thing.

ok got the point but will I be able to change the sizes of the buttons
once I tell the box to lay them on the screen?
I will like to make some buttons a bit small and add more space to
give some additional visual hint.

can a spacer be altered for different sizes and how?  I don't have a
comprehencive tutorial on these layouts and will surely like to try.

I want to know if my code will become to complex if there are two many
controls and if yes how to avoid it?
