Is there a way to set/unset the execute bit on a file in osx 10.6.8 without using terminal (or bypassing it)? I would like to do the following: 

chmod +x filename.txt


without using the terminal.  Is there a way to bypass the terminal and invoke a kernel system call ? I'd rather not write a program to do this.  Instead I was wondering if I could somehow simulate a terminal with (perhaps) an application besides terminal to invoke system calls. 

I have already tried doing Command Key + i on the file to show the information GUI.  However there is no option for setting the execute bit. 

Would appreciate help from os x administrator experts in the community.
Keyboard Maestro can do this using the following macro, which runs chmod +x on each item in the current Finder selection:
