If by framework you mean web framework, I've used Dropwizard. It's a lean and mean modern-java option, and it's not a Kotlin native thing (you do have these). You can use any Kotlin or traditional Java framework out there transparently (that's a good value of Kotlin).
For ORM, Dropwizard and its ecosystem got you covered.
Also dropping out to Java when ever you want can be done in the same project (which I encouraged) seamlessly both in terms of how Java and Kotlin interoperate, and in terms of Intellij, which is first-class in both languages because Kotlin is Jetbrains' baby, and, because Java has been best supported by Intellij for ages (can't really find that kind of thing anywhere else).
