Need a comprehensive C++ library

[Francisco Santiago Capel Torres <santiagocapel yahoo es>]

Hello list:

I have been developing for 2 years with Qt. I have developed a GPL report 
engine http://reports.sourceforge.net
Now, I want to abandon my Qt develpment and port it to GTK-- and STL.

I will replace all the Qt container classes with the STL ones.
My program doesn't use a lot of windows, so this is not an important issue.

But there are a few issues that concern me, and I need your advice:

a) What is the basic String type in GTK--? Does it support unicode? Can I use 
the STL string?

b) Are there Date, Time and DateTime classes?

c) Is there a nicely packed c++ library with all the elements that I used to 
have with Qt, like XML, SQL, etc?
	c.1) If not, what library can I use for SQL? It should be really 
light-weight, just a wrapper for the MySQL and PostGreSQL servers.
	c.2) For XML, I only need a SAX parser.

d) Is there a library for scripting like QSA? I don't need the signal/slots 
mechanism of Qt, just a light-weight expressions evaluator. I have even 
started to build my own one with lex and yacc.


I don't think these are big issues, I just need a bit of advise to start 
quickly with the best options.

Thanks in advance.
