Mix Jython and Java

I want mix Jython with Java projects. For example I want use GUI Designer for swing forms in Java project, then use the forms in Jython project.

When I create python project with Jython SDK I can use swing directly, but can't add swing form from Intellij GUI. Then I try to create new java module in same project and create swing form in the module. I can do it, but I don't see the swing form from Jython code.

Is any way use Jython and Java in same project (and use GUI designer for swing in Jython project)?
