It is not possible to calculate PageRank without querying Google. There are plenty of scripts to display PageRank.
I guess displaying google page rank is not against google TOS because there are lot of site out there displaying page rank result on their sites.
The script is here. The best thing is to do a weekly query using a cron job and store the results in the database. PR only updates 4 times per year so you could even just hard code the image into the page and just update it when the PR updates.
