It depends on how you are implementing your action, but you may already have a dialog in your custom action client side code.
Within that dialog you can define the template to be a custom webscript (Share tier)

...
templateUrl : Alfresco.constants.URL_SERVICECONTEXT + "yourCustomDialogWebscriptURL?nodeRef=" + file.nodeRef,
...

In that webscript controller, you need to call api/version for your node, something like this

...
var getVersionsURL = "/api/version?nodeRef=" + args.nodeRef;
var connector = remote.connect("alfresco");
var result = connector.get(getVersionsURL);
if(result.status == 200)
{
 model.versions = JSON.parse(result);
}

...

And finally you can iterate the versionHistory in the dialog freemarker template, something like this

...
<select name="versionSelect">
 <#list versions as version>
 <option value="${version.label}">${version.label}</option> 
 </#list>
</select>

...

finally, this is an example json returned by api/version

[
 {
 "nodeRef": "versionStore:\/\/version2Store\/ee0c0cde-db24-40eb-835c-a81478da9535",
 "name": "Project Contract.pdf",
 "label": "2.1",
 "description": "I made so many changes to this doc",
 "createdDate": "01 dic 2016 12:07:11 GMT+0100 (CET)",
 "createdDateISO": "2016-12-01T12:07:11.365+01:00",
 "creator":
 {
 "userName": "admin",
 "firstName": "Administrator",
 "lastName": ""
 }
 },
 ... 
]

I hope it helps

Hi Mikel,

Sorry, I know it is a bit late but I got involved in other stuff and kept this on the back-burner. So, I was trying what you suggested above but instead of calling a custom share side webscript which would call the versions webscript I called the versions webscript directly from the ftl script tag. The issue I am facing here is that I am not able to get the nodeRef of the document. I tried getting the nodeRef by form.arguments.itemId as suggested by Alex in my other post here but it gave me version-delete as value Below is the ftl.

<code>

<#include "/org/alfresco/components/form/controls/common/utils.inc.ftl" />

// supplementing hardcoded noderef just to check if the ftl works; needs to be replaced by object containing noderef. YAY!! it works.
url: encodeURI(Alfresco.constants.PROXY_URI + 'api/version?nodeRef=workspace://SpacesStore/284202aa-e21f-4e23-bf18-b163c4d9fa49'),
successCallback:
{
fn: function loadWebscript_successCallback(response, config)
{
var obj = JSON.parse(response.serverResponse.responseText);
if (obj)
{
for (i = 0; i < obj.length; i++) {
var newOption = document.createElement('option');
newOption.value = obj[i].label;
newOption.text = obj[i].label;
YAHOO.util.Dom.get("${fieldHtmlId}").options.add(newOption);
}
// Current value
var sp = document.getElementById("${fieldHtmlId}");
sp.value = "${field.value}";
}
}
}
});
}, this);
//]]></script>
