CMS Grid: two horizontal widgets in additional footer?

[ceho]

Hi, I would like to create a grid with one column for the primary content, a sidebar on the right and an additional footer. No problem so far.

However I would like to have two widgets within the additional footer, but they should be placed horizontal and not below each other (example with several horizontal widgets can be found here: http://www.swishzone.de).

I read through various posts here, and found out how to flatten a grid. I also copied and played around with a couple of codes (I found e.g. the one from Lynne where you have two or three horizontal widgets on top of the primary content), but I am perfectly stuck. Could someone please help me finding the right code? I am totally lost with all the YUI orders, and the result I am thinking of is actually looking so simple...

Any help is much appreciated.
