haven't built anything like this, but this would be one approach.

find yourself one of the many scripts out there that places a "bug" in the
bottom-right corner of your browser window.  modify the script so that it
shows the "back to top" link/icon if the page is scrolled more than a
defined number of pixels down (look at the scrollTop property for this
info).

for backwards compatibility (yes, it's possible), place the "back to top"
piece as the last item, right-aligned, at the bottom of your content.  take
a look at how it's been done on a site i built recently.

non-js browsers and browsers that don't support the scrollTo() method will
jump to the #top bookmark i've included in the source.  otherwise the
browser window is simply scrolled to the top (0, 0).

good luck,
