[fpc-pascal] GTK2 Lazarus Project, but I want QT.

One little question:

- how do I read the Qt docs? Do I read the official one and hope that the 
C/C++ Qt functions have the same name in FPC? Or is there a deposit for this?
- do I import the Qt units in FPC to make that program or do I use the Lazarus 
Source code editor without a form [visual design IDE] as it would be easier?
- Any other info you could tell me that may be usefull? Of course, I'll tackle 
these cosmetic bugs as soon as my GED is over. [General Education Development 
Test. :P I just finished high-school and taking my big exams now in hope that 
I'll end at the Politechnic Faculty in Bucharest :D so time is of the esence 
right now].

Sorry to ask you such questions, but information is quite sparse.
