Is it possible to add a button on the JIRA Dashboard that when clicked interacts with Bitbucket?

We would like to add our own custom button on JIRA that when clicked pulls specific data from Bitbucket like files (not file names), associated with a particular commit.

You can try using custom JIRA Gadgets, but I don't understand your use-case why do you want to pull files? where do you intend to store these files as bitbucket is meant for storiing files and jira can display those fileName (it already does that in the "commits" tab if you have bitbucket and jira connected via application links)

[Siyanda Mzam]

We would like to pull the files so as to be able to send them to an external client instead of having to manually go through commits, finding changed files and sending them via email to the client.

So the idea is to have a button that when clicked simply gets all the changed files, zip them up and send to the client.

You'll need to write the code behind that function, and bind it all to a "web fragment" (snippet of html that JIRA recognises as being part of a menu or screen)

As usual, I'd do this with ScriptRunner, because I know it can do the get-and-send you need, plus tie my code to a web-fragment very easily.
