Editing a site widget from the dashboard?

Hello! I had trouble Googling this because the dashboard widgets are called widgets, and I’m looking to be able to edit one of my site widgets (also called widgets) from the dashboard.

So is there a relatively easy way that I can create a dashboard widget that will allow me to edit one of my website widgets? I only need to be able to edit the one, I don’t need to be able to select between them or anything like that.

Thanks.
