In 2004, we developed (in house) a simple VB system tray application to remember passwords and prompt links to important web pages, etc.
It's not quite out of date, as is our programming experience so we'd like it re-developed.
The Windows apps should work with XP, Vista (and pref Win 7) and include installation software.
Very simply, it installs and sits in the system tray. When right clicked, a bunch of menu options appear. Most will lead simply to web links (to open in default browser). Software will also need to store login passwords (locally and securely) to enable fast login to web services plus a few other things which are easy coding.
This is not a complex job and for an experienced coder should be a doddle!
We originally used VB6 but I guess you can use whatever you like! Original app available for viewing on request.
