Why Plone needs Midgard

Recently , I followed these threads:

• Let's build www.gnome.org on top of Plone
• a war against Plone

I wonder how Zope and Plone can be extended?

Can I use Java with Plone?
Can I use PHP with Plone?
Can I use pure GTK+ with Plone?
Can I use SQLite or PostgreSQL or MySQL with Plone?

I wonder about such sentence:

If you can see the beauty, then Python got you

And I wonder about comprehensive and standardized tools which can be reused in any environment.

Zope and Plone developers, Midgard uses GLib and GObjects as its base. If you need to extend Zope , just use Python language bindings for Midgard. It's easy.

I can of course implement PHP bindings for Plone.
