Software/devops engineer's personal dashboard recomendations
For all of your read-only dashboard needs, there is Grafana with multitude of plugins, data sources and visualizations (tables, charts etc). You can also program your custom data sources pretty easily with official "simple-json-datasource" plugin.

By default, Grafana does not support buttons or other kind of form/action stuff on its own. Grafana is all about visualizing data, not modifying it. Yet, while I haven't tried it myself, Grafana supports Text/HTML/Markdown panels, I think you can implement any JavaScript logic inside those panels.
