Quark doesn't have automatic bulleting, but two options leap to mind to fake it:
1. Create a paragraph style with a hanging indent. The first character of the paragraph will be your bullet character; tab after the bullet character to the actual first character of your paragraph. If you want to, style the bullet character using a character style so in case you change your mind about the formatting of the bullet character (say it's a 9 pt red Zapf Dingbat and on reflection you decide you'd rather have it at 8 pt and in gray).
2. Create a paragraph style with a hanging indent, and fake the bullet with a paragraph rule.
The former's more flexible and works in more situations; the latter's more automatic; take your pick.
