can program my router to pick up the wifi signal from the next office and
get it into my box? F7 if it matters.


 
Yes it is possible to setup a something like that is you have a WRT54G that supports DD-WRT. 
 Go see if your version is support here: http://www.dd-wrt.com/wiki/index.php/Supported_Devices

If your WRT54G is supported then you can flash the WRT54G with the dd-wrt firmware.  Once flashed you can have your router be a wireless bridge to the other wireless network.  There are some other steps that I am leaving out because I do not remember them all as it has been months since I setup something like this.
