Both ECB and gdb-ui (the graphical part of GUD) use something called
dedicated windows.  This means that they're protective over their
window configuration and won't let other buffers display in their windows.

Maybe 'C-x 5 2' (opens a new frame) followed by M-x gdb-many-windows in the
new frame will work

I think there will always be conflicts without a major redesign.  ECB isn't
part of Emacs and I've never really used it.  Ideally ECB would be integrated
into Emacs but that would be a lot of work and I don't think it's going to
happed anytime soon.

If simsoup is a large program and you really need a project based development
environment you may be better off using Eclipse with CDT.  I guess I shouldn't
really be saying that on help-gnu-emacs and you will have to recommend the use
of GDB in Emacs to others as a daily pennance!
