The current group of CC licenses should not be used for licensing software.  
See
http://creativecommons.org/faq#Can_I_use_a_Creative_Commons_license_for_software?
for more on this.

I don't think that copyright law gives you the power to prevent this.

I think that proprietary software is untrustworthy by default.  I don't think
that your software will be interesting to anyone who makes websites if you
license it under such restrictive terms.  There are plenty of free software
programs (software users can run, inspect, share, and modify at any time for 
any
reason) to do the same job.  Perhaps licensing your software to allow users 
these freedoms will make your program more attractive?

Again, the CC organization has "wrapped" the GNU General Public License at 
http://creativecommons.org/license/cc-gpl and there you can find out more about 
the GNU GPL.

As long as the copyright is yours on the software, the copyright to that 
program
would remain yours even if someone made a derivative version of the software.
The other copyright holders would hold a copyright to their changed portions.
More complex arrangements are possible, depending on how you licensed the
software.
