Create a page selector using taxonomies

Create a page selector using taxonomies

I have created a custom post type and assigned a term from a custom taxonomy to each page within this CPT.
I want to create two select boxes on the front end of my site.
I want the 1st select box to display the custom taxonomy terms.
Once someone has selected a term, I want the 2nd select box to display the pages assigned to that term.
I then need a button that will take me to this selected page.
If anyone could help with this, that would be great.
