Advice on Qt User interface

[Hugo Pereira Da Costa]

Hi,

Newbie question. What's the policy on designing user interfaces (Qt 
based) in KDE:
use UI files rather than brute force c++, or indiferent ?
I personally hate Qt designer (for my own reasons) and have been used to 
design my UI in brute force c++.
Are there some known disadvantages with this approach ? Or historical 
reasons against it ?

Thanks in advance,

Hugo
