How to create a simple list of links to Drupal panel pages?
You could create a View of miscellaneous page links, if the list of links was actually a list of a series of nodes with a particular taxonomy term applied to them.

For example:

Create a taxonomy vocabulary called "Page Links", and create a new taxonomy term for it called "Custom Menu One". Then, tag each of the pages which you want included in your list of links, with this Custom Menu term.

Now, you can go into the Views UI, and create a block View which outputs all nodes which have the taxonomy term "Custom Menu" applied to them. You can set up the view to use fields, and output the title of each node as a link back to the original content.

You'll also be able to configure the display settings for the View so that the links are output as a List, or Table, or unformatted, etc.
