Hole thru the wall (or if the hamshack is in the basement have foundation 
core-drilled). Cover hole with a NEMA box (or similar); the NEMA box is 
suitable for external ground point, addition of terminal strips for rotor 
control, add Polyphasers, etc. Terminate the coax inside the NEMA box, then 
add jumpers as needed to run into shack. This way you can switch 
antennas/rigs, change connector types/genders, etc.

Balanced line can also exit the building thru this box by using a pair of 
coax cables as a short run of balanced line. Once outside the building, 
mount a pair of standoffs on the NEMA box, and connect the two coax lines to 
the standoffs. I you want to get really fancy, use a pair of lawn mower 
sparkplugs as the standoffs, they will also act as spark gap lightning 
suppressors if you ground the box.

Not as fast & easy as Mike's approach, but keeps the XYL happy (cosmetics) 
and is quite flexible for when you make changes to the shack, rigs, anetnna 
farm.
