vba - Insert a word from a predefined list of words -

i'm looking way create vba script in ms word displays list of predefined words. if user clicks on one, inserted document. google searches showed way create mailings values excel want words hard coded inside vba script (array maybe?) without external files. here small mockup how imagined it:

any ideas or tutorial links on how achieve somehing this? doesn't have dialog in image have collection of words in dialog user select.

edit: nice if user see human readable label (like 'first name') inserted value variable (like '$firstname').

for creating pop-up list of words, can try this connect displayed value actual value.

as inserting text part, this post seems address topic. otherwise here's msdn (http://support.microsoft.com/kb/212682/en-us)
