Is Kosmos a simple front-end to JIRA, Subversion and SourceForge?

Something like that. It's actually a way to integrate JIRA/SVN/CC/SF into your JSR-168-compliant portal and to track the appropriate resources...

I use CVS for version control and ITracker for issue tracking.
Can I addapt Kosmos to use these Softwares?

At the moment Kosmos doesn't support these. (As a matter of fact, CVS support is already planned.)
But, hey, this is open source software, plz go ahead and implement it, I'm happy to help you. And/or place a feature request in our JIRA.

Why JIRA? It is not open source...

You're right, JIRA is not open source, but IMO the most widely used issue tracker for open source projects (as Atlassian provides it for free as far as I know for serious projects).
