Adding buttons to custom admin page

<%= t 'js.tagging.tags' %>: <%- @topic_view.topic.tags.each do |t| %> <%= t %> <%- end %>
<% end %>

Question:

Hello

I am new to Silverstripe. Was wondering if someone could confirm, and possibly show an example if it is possible to add buttons to a custom admin panel which can trigger methods.

Cant seem to find anything on the docs page.

Thanks,
Blake
