I think you should familiarize with AppKit first. Do it on the mac with 
a tutorial for 10.2 ... 10.4 and you should find concepts very similar 
to GNUstep. and quite applicable. We support also 10.5 and 10.6 
features, but the developer app paradigm did not follow apple's.
We still distinguish between the project builder and the interface 
builder and I'm happy it is as it is, apple is changing many thing 
gratuitously so it can make shiny new features which each release.

As "Title" do you mean a box? You may edit some properties in the 
inspector, some other direclty by double-clicking the text in the window 
(sometimes triple-click, the first needs to select the item)

Exactly like in InterfaceBuilder: ctrl-drag from source to target, then 
int he inspector select the action or outlet. Beware that it needs to 
exist. To do this you either need to load the class to parse the header 
(you can quite safely reparse it) or add it manually with the correct 
name. You you can create all outlets and generate the headers automatically.

that's obj-c 2.0 stuff. You need gcc 4.6 or clang.

You may want to check out the classic calculator tutorial by Pierr Yves 
which was recently updated to current gnustep tools.
