I want to be able to create a custom form with multiple columns
Dont known exactly what you mean as multiple colums, but you can use html table structure or for two colums JIRA used predefined styles, something like:
<div id="primary" class="column">...</div> <div id="secondary" class="column">...</div>
For more details, check some existing html souce code, like ViewProfile.jspa
