Cool that actually works! Thank you very much. I have rerouted the  
logging stuff wget outputs to /dev/null, as I'm really not interested  
in that:

Code in button:
on mouseUp
   launch "path/to/script/file" with "sh"
end mouseUp

Code in script file:
#!/bin/sh
wget -P/path/to/folder http://url.written.wrongly.on.purpouse.by.bjoernke.com 
  > /dev/null


Have Fun
