Yes. In fact, something like that existed in the runtime a while ago. However,
you can achieve mostly the same by writing your own WinMain as shown here:

http://dlang.org/windows.html

This page is a bit outdated. Note the exceptionHandler parameter: this is the
mechanism mentioned above that no longer works, and those overloads of
Runtime.initialize/terminate are now deprecated. (Martin Nowak removed them in
b95be7e55e57a4ff065f1dc5f3362fc476d85f4d. Before that, Walter Bright wrote in a
comment: "Note that if we get here, the runtime is in an unknown state. I'm not
sure what the point of calling dg is."). However, the general idea still works,
if you don't care about exceptions thrown during runtime initialization /
deinitialization (this includes static constructors/destructors). Just replace
the MessageBoxA call with your custom error-handling code.
