You're using Windows XP, so you should have Windows Scripting Host installed by default. With that being said, here's a WSH JScript script to do what you need. Just copy the code to a file name xtract.bat or something along those lines (Can be whatever as long as it has the extension .bat), and run:
xtract.bat example.tar.gz
By default, the script will check the folder of the script, as well as your system's PATH environment variable for 7z.exe. If you want to change how it looks for stuff, you can change the SevenZipExe variable at the top of the script to whatever you want the executable name to be. (For instance, 7za.exe or 7z-real.exe) You can also set a default directory for the executable by changing SevenZipDir. So if 7z.exe is at C:\Windows\system32\7z.exe, you'd put:
var SevenZipDir = "C:\\Windows\\system32";
Anyways, here's the script:
@set @junk=1 /* vim:set ft=javascript:
@echo off
cscript //nologo //e:jscript "%~dpn0.bat" %*
goto :eof
*/
/* Settings */
var SevenZipDir = undefined;
var SevenZipExe = "7z.exe";
