Tutorial for DB-Frontend with GUI

[Al Bogner]

Since weeks I am searching the net from time to time how to build a
small MYSQL-Frontend for a simple small database. The last decision
ist not made, but it looks like, that I will learn Python.

The (non-commercial) DB-frontend should run on a Linux-system only
and it would be nice, but not necessary, if the program could be
ported to Mac or Windows later for free.

I found a lot of interesting links like

http://wxpython.org/
http://boa-constructor.sourceforge.net/
http://www.die-offenbachs.de/detlev/eric3.html
http://doc.trolltech.com/3.2/designer-manual-8.html
http://doc.trolltech.com/3.2/sql.html
http://vtcl.sourceforge.net/
http://starship.python.net/crew/mike/src/Spectix/Spectix.html
http://pythoncard.sourceforge.net/

It's hard to decide, which one is the easiest way for for a
python-beginner. How reliable is boa-constructor? 0.2.3-alpha seems
to be not very stable.

So, does anyone know a tutorial/howto/link or whatever how to build
a database client with a GUI? Is there a sample database-fronted
built with python in the web, where one can see what is possible?

All recommendations are welcome!
