I assume you access GeoServer via a URL like 
http://localhost:8080/geoserver

If so, then http://localhost/geoserver/wms (used below) will only 
resolve to your WMS endpoint if you set up a proxy.

If you don't want to set up a proxy, you can dump things in the www 
directory in GeoServer's config directory.  Assuming you place a page in 
there called basic.html, it will be accessible via a URL like 
http://localhost:8080/geoserver/www/basic.html

If your html uses relative URLs to pull in additional resources (like 
OpenLayers.js), then those resources must be located relative to your 
basic.html page.

None of this is really OpenLayers specific, but if you have additional 
trouble getting OpenLayers to load, send more detail.
