I have following in existing gradle based project that I'm trying to get working with amper....is there way through gradle interop to allow this?

sourceSets {
        all {
            languageSettings.optIn("kotlinx.cinterop.ExperimentalForeignApi")
        }

You should be able to specify opt-in annotations directly in your module.yml settings (no need for Gradle interop):

settings:
  kotlin:
    optIns: [ "kotlinx.cinterop.ExperimentalForeignApi" ]

See: https://github.com/JetBrains/amper/blob/0.2/docs/DSLReference.md#kotlin
