Given your other thread is about having multiple "wallet.dats"... then I'm guessing you simply want to know what the balance of a given "wallet.dat" is? Is that correct?
If so, then your choices are basically "Bitcoin Core" or "Bitcoin Core" or "Bitcoin Core"
The wallet.dat format is quite specialised and there are no other applications that are able to read the wallet.dat format that Bitcoin Core uses and display the addresses and/or wallet balance. PyWallet would probably have been the closest... but that is simply a python script, and is horrifically out of date and not very functional with updated wallet.dat files.
Otherwise, you could probably use PyWallet to dump out the addresses in a wallet.dat file and then run a script that queries a block explorer API to see what the current balance of those addresses is... I'm not aware of any "ready to go"/"off the shelf" scripts that do this at present.
