your answer and Kevin`s answer were really helpfull!
What I am going to do is to check if the user is using Linux* and In that case I will try to get the proxy settings from http_proxy environment variable or from gconf or from kioslaverc. And if everything fail I will ask the user to provided the correct proxy settings (I think this is a fair solution because on one hand I think most linux users know what a proxy is and on the other hand at least I tried to get things easier for them :-) )
Probably I will download a KDE distribution to test my code or at least I will find someone using KDE (and willing to do a test for me).
* (I use a python library call mechanize, in Windows and Mac OsX, this library reads the proxy setting from windows registry and some MacOsX registry)

replying to, thus maintaining the context. It makes further followups
/much/ easier. =:^)
As with Kevin, I don't authenticate to my (localhost-only, personal)
proxy, so can't confirm the username/password bit. But, some more to
add...
"IMPORTANT*: That should be --key httpProxy (case sensitive, uppercase P
on proxy), or it returns nothing. See below.
FWIW, here on Gentoo, the kreadconfig binary is part of the kreadconfig

package, which is a dependency of the kdebase-startkde package.
What that means "in plain English" is that it will be installed as part of
the infrastructure for actually starting a kde session. So anyone running
a kde session should have it installed (at least on Gentoo), but not
necessarily anyone simply running a kde app on some OTHER X session
(gnome, xfce, whatever), since it's not included in or a dependency of
kdelibs, a dependency on which is (by some practical definition at least)
what makes a kde app.
It's also worth noting that kde's config (as read by kreadconfig) is a
composition of data from several locations. Normally, there will be at
least two config locations, one each in $KDEHOME and $KDEDIRS (with
appropriate defaults for each if they aren't set, often $HOME/.kde/ and
/usr/share/, but a distro may have other defaults), with the possibility
of config files in either or both locations. It's thus possible for a
sysadmin to have a kioslaverc file at /usr/share/config/kioslaverc that
would contain settings for all users, that would be read first, so the
user settings (if present and if a value hasn't been set to prevent it)
override the system settings.
kreadconfig combines the data from all the files in all locations in the
appropriate stack-order, so the data read is the same as if a kde app was
reading it using (presumably) kdelibs functionality. It's thus a MUCH
more appropriate way of reading the config, than to try to read it
directly from the config files yourself, even if it doesn't interpret what
it returns, that's upto the script/app calling it.
The caveat is that for kde apps installed alone, not with the
infrastructure necessary to run an entire kde session, kreadconfig might
not be available.
Here's my user config kioslaverc here; no system kioslaverc (and the user

one is $HOME/kde/share/config/kioslaverc , no leading dot-dir, as I
dislike hidden major config dirs so set $KDEHOME appropriately,
NoProxyFor and the httpProxy port slightly obfuscated)

Given that config ($>> indicates my shell prompt):
$>>kreadconfig --file kioslaverc --group "Proxy Settings" --key httpproxy
$>>kreadconfig --file kioslaverc --group "Proxy Settings" --key httpProxy
http://localhost:nnnn

Note both the quoting of "Proxy Settings" so it is passed by the shell
as a single parameter, and that the whole thing is case sensitive
(httpproxy as the key returned nothing, neither would "proxy settings"
as the group, or KIOSlaverc, since in each case that refers to an
entirely different and here non-existing object).
