Not really, you just need to separate the concerns of your app properly (this is a case when some layering would be beneficial).

They certainly don't have to (and I prefer they don't, this was something we experimented with early on and have since swung away from, preferring to manage the entity beans using a Seam manager component like EntityHome and a factory).

So, keep your business logic in e.g. EJBs, and provide two facades, one for Web apps using Seam and one for Swing using whatever you want. (Btw Seam doesn't really support Swing at all as a front end).
