I'm stretching my memory here but as Marco indicated, wxWindows wasn't 
mature at the time. Also if I remember it didn't deal with signals well 
at all. Secondly at that time it did not support GTK. It only supported 
Windows and some Xt and Motif.

It is also written in and for C++. Sooooo this is what we would have 
been doing.

The LCL needs to be not only widget set independent but platform 
independent. If we wrote the LCL just to wsWindows then we would 
eliminate the possibility of using Lazarus on other platforms that FPC 
supported. So we made an abstraction layer between the LCL and the GUI 
widget set being used. So using wxWindows for GTK would mean.

LCL -> LCL/interface -> C++ wrapper -> wxWindows -> GTK+

Not only would we have to write the interface for wxWindows but it would 
have to be a wrapper around C++ since FPC doesn't support C++ directly. 
Alot of extra work instead of going directly to GTK. Besides as I stated 
wxWindows didn't support GTK at the time. This would have been wxWindows 
1.0 and you can still see what it supported by going to the their web site.
