NNTPGrab

That depends on the operating system you're using.
By default, NNTPGrab uses the same language as configured in your operating system, so if you change the system language, the language used by NNTPGrab should get changed automatically as well

Note that you also can change the language from the commandline with LANG=xxx.

Supported values are:
LANG=nl_NL nntpgrab_gui
LANG=en_US nntpgrab_gui
LANG=fr_FR nntpgrab_gui

I have tried this also with the SET command but can't get it to work. Were are all the settings saved? In the registry ?

As you're talking about the 'SET' command, I assume that you're using a Windows environment.
For Windows environments, the language which is set up in the control panel is used (on Windows 7, this is the Region and Language component).
If you want to change the language of NNTPGrab only (without influencing other programs) you can
start cmd.exe and use the following commands:

cd "C:\Program Files\NNTPGrab\bin" 
set LANG="nl_NL" 
nntpgrab_gui.exe

The value nl_NL causes the Dutch translation to be used. For the English translation, use en_EN and for the French translation use fr_FR
