I’m not quite sure I understood what you want to achieve, but here we
go: I tried with xfce4-terminal, but that should mostly behave the
same as uxterm. Essentially, there are two problems to solve here:

a) xfce4-terminal -e /bin/bash -c /usr/bin/mc

is read as the "-c" option by the terminal, not the shell. We need 

$ xfce4-terminal -e "/bin/bash -c /usr/bin/mc"

to pass -c to bash rather than xfce4-terminal.

b) Furthermore, bash appears to have no option not to exit after the
command passed via -c exits. However:

$ xfce4-terminal -e "/bin/bash -c \"/usr/bin/mc && /bin/sh\""

runs /bin/sh after /usr/bin/mc exits sucessfully (use ; instead of &&
to ignore return codes).

HTH & Best,

Claudius
