I suggest that you avoid the GPL for components, as GPLed components
can only be used to build GPLed applications. Alternatives are:

the LGPL at http://www.gnu.ai.mit.edu/copyleft/lgpl.html;
the MPL at http://www.mozilla.org/NPL/MPL-1.0.html;
the BSD license (aka "James Clark" license)
at http://www.opensource.org/bsd-license.html
the public domain.

I favor the last two options for large and small components
respectively.

For information and texts, see http://www.opensource.org .

Also note that modified versions of the GPL are *forbidden* by its
own copyright notice: the GPL is not itself under the GPL, but
under a license that says "anyone may copy, but changes are forbidden."
That is to prevent the proliferation of minutely different versions
of the GPL.
