Clicking on the IDLE icon is fine - unless it is doesn't work, in which 
case error messages associated with the failure may end up in a system 
log rather than being display directly to you.  It's easier to debug 
problems like this by launching IDLE from a terminal session than by 
double-clicking on it.  Assuming you installed Python 3.4 (3.4.1 is 
current) from one of the python.org installers, open a terminal shell 
window, for example by using the Terminal.app (found in 
/Applications/Utilities).  Then, in the shell window, try typing:

/usr/local/bin/idle3.4 

If IDLE fails, there should be some sort of error message in the 
terminal window.  If it is not clear what the problem is, copy and paste 
them to the group here.

You can also just try launching Python itself and verify that it works 
without IDLE:

/usr/local/bin/python3.4

Good luck!
