No you can have as many top-level classes as you like, both extending java
classes or not.
The class with the same name as the file will correspond to the class produced
by jythonc
(btw the other classes extending java will correspond to inner classes of the
main java one (not that
much important), the purely python classes have no such correspondence at all).

For the rest you should consider that jythonc does a static analysis in order
to
understand which classes extend java classes, something plain as

from javax.swing import JApplet

class MyApplet(JApplet):
  ...

import javax.swing

class MyApplet(javax.swing.JApplet):
  ...


should work.
