same way you'd do the normal site with a information table in it..
Say you got a table with 3 rows..
row 1 contains your header
row 2 contains 3 columns, left column would have the left graphics for the table, center column would have the board, right column would have the right graphics.
row 3 contains the footer graphics..
pretty easy actually. Just make ya normal code then find out where a table would go if you wanted to insert some news or a picture in the center of the page, take and highlight all the code above it and paste that into the header box under your style template, then take all the code below that table and plug it into the footer box in style template.
Done.
