user3866: I am trying to setup GUIMiner together with mining.bitcoin.cz. As I am working on a laptop with an Intel graphic card I am (probably?) unable to use GPU mining. So, just for a test, I tried to run GUIMiner without GPU support, that is as a CPU miner (if this is the correct word).
Clicking the start mining button doesn't seem to make anything run. I might be mistaken, but the lower right corner of the application keeps saying stopped.
The console tab says:

2013-04-03 17:51:51: Running command: poclbm.exe :@api2.bitcoin.cz:8332 --device=0 --platform=0 --verbose -r1` 

But no error message, either.
So, I go to cmd.exe and copy poclbm.exe ***:***@api2.bitcoin.cz:8332 --device=0 --platform=0 --verbose -r1. This results in 
No PyOpenCL
Not using OpenCL
Nothing to mine on, exiting

which can be taken as an error message. I believe that "OpenCL" indicates that the program wants to use a GPU (although) I am not sure. I just want to test the mining functionality and see if I can particiapte in the mining pool, at the moment without graphic card, only the CPU. Is this somehow possible?

user2306: If you start the bitcoin-qt client from the command line with the bitcoin-qt.exe -gen 1 command, then it will generate bitcoins using your CPU. Alternately, use cpuminer. (Builds)
