How to create a grid file

Hi everybody:
I want to create a grid file for export to statistical program.
My aid is create a file with both rows, one row are x coordenates and other for y coordenates.
All grid obviousolly are same space.
the form that i want is this:

x=(400000 ........ 600000) and y=(4000000 ....... 4550000), the increment is 10000 and then appear a matrix like:

(600000,4550000)----------------(800000, 4550000)
. .
. .
. .
(600000,4000000)----------------(800000, 4000000)

The statistical program read the file for rows.
It's possible do it with awk, or it's better do it with other language.?
Thanks in advance.

You could do this in awk, but that may not be necessary. It is possible to do this in sh/ksh as well.

When you say 'better' what exactly do you mean? A solution in awk is perfectly valid.
