The following site is a great source for portable apps.  There is just about everything you might need such as FireFox, Thunderbird, Open Office, Gimp, VLC, PuTTY and lots more.  http://portableapps.com/suite
For anyone who is familiar with TrueCrypt (http://www.truecrypt.org/), it is possible to install the portable apps suite into a TrueCrypt 'encrypted container', which not only protects the applications and any associated files you may have created with them, but which can be copied to whichever device you want to store and run the applications from (USB Stick, PC, laptop).
