I had a similar problem and wrote a small html page with embedded javascript. It checks the blockexplorer and the exchangerate and produces a nice web page where it lists all my accounts, with my btcs and converted into EUR - without having to start the bitcoin client with my wallet and the private keys.
There are 4 files you need, bitcoin.js with the script funcitonality, config.js (where you should edit the addAccount lines, replacing the FILLIN stuff with your bitcoin addresses, style.css for some cometics and sum.html as main file. I am using a bit of jquery, so you should make sure that all files including jquery_min.js (to be picked at the jquery website) reside in the same directory.
Then just load it with firefox version 3 and confirm the security dialogue. You will have to navigate to about:config and set signed.applets.codebase_principal_support to true as well.
I am including the files below. They are very far from perfect but help me solve my problem. They do not run in firefox 5 (mozilla removed the privilege manager), but version 3.6 is fine for this purpose. Do NOT put the code on a web server, it has security issues if you do not understand what I am doing here.
=== config.js:
// URL of the block explorer
const SERVICE_URL = "
http://blockexplorer.com/address/";
// URL for the exchange rate
const EXC_RATE = "
http://bitcoincharts.com/t/weighted_prices.json";
// default exchange rate
const CURR = "EUR";
// default weighting
const WHEN = "24h";
addAccount ("1PFILLIN", "Eligius");
addAccount ("1FILLIN", "Other");
fakeAccount ("1PRCQbVgLkNjUCWafA8UYsmBH1Ay7zyvu8");
exRate();
