Just common sense of ergonomic UI, because I am no expert in this.

I do not like dialogs because they cover other UI elements and require 
switching user attention.

If I need some input field I usually reserve a place on the screen with 
confirmation and cancel buttons. I try to implement 
checking-while-typing when possible and not too annoying.

A confirmation/commit button is IMO preferable, however modern UIs tend 
to commit changes as soon as the UI element loses the focus.

For settings I use tabbed views. They tend to grow out of any measure. 
Not a perfect solution, but IMO much better than dialogs and in any case 
better than tree views when you need to expand and collapse nodes 
looking for a setting parameter.

Modal dialogs are OK for emergencies when continuation is absolutely 
impossible without user intervention.

One of few advantages of GTK is that widgets and containers 
automatically expand and shrink. One should use this feature and avoid 
fixed sizes. The minimum widget size, e.g. of a label or edit field can 
be set.
