Toad by Quest Software was the original SQL GUI development tool, and developed the basic style that most of these apps use today. I have senior developers who refuse to consider anything else, and cling to unsupported versions of Toad. Oracle SQL Developer does not support SQLite, but the design is their "internal Toad-killer," and reimplements Toad in Java. It does accept JDBC drivers for 3rd-party databases (but not SQLite so far).
