There was a recent thread on the list about enabling a plugins
interface for the IDE (or any other Gambas app). With the current
tools made available to the developer, the DBus component is the
closest thing to what you are looking for. The "context" could be a
DBusObject, which any other application can call, either made in
gambas or not, you only need a DBus interface. See this link [0] for
an example. The full thread is available here [1].

Another way, but possibly really hard to code for it to be safe, would
be to use the Component.Load [2] function. This would give the said
component full access to your app, but maybe that's not what you are
looking for.

Hope this helps!
