You can use wpa_cli or wpa_gui in the same way in both modes.

Example: I have a wpa config file only for my home adsl.
============================================
iface eth1 inet dhcp
  wpa-conf /home/zhang/.wpa/wpa_supplicant.conf
  pre-up modprobe bcm43xx
  post-down modprobe -r bcm43xx
  post-down modprobe -r ieee80211_crypt_tkip
=========================================

and
=========================================
ctrl_interface=/var/run/wpa_supplicant
network={
  ssid="myssid"
  key_mgmt=WPA-PSK
  proto=WPA
  pairwise=TKIP
  group=TKIP
  psk="mypasswd"
  priority=5
}
=======================================

When I am not at home, if I run 'ifup eth1', I can not get a connection and I
see
=======================================
# ifup eth1
Internet Systems Consortium DHCP Client V3.0.6
Copyright 2004-2007 Internet Systems Consortium.
All rights reserved.
For info, please visit http://www.isc.org/sw/dhcp/

Listening on LPF/eth1/00:11:24:22:f5:04
Sending on   LPF/eth1/00:11:24:22:f5:04
Sending on   Socket/fallback
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 5
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 13
...
...
=======================================

But if I run then wpa_gui (or wpa_cli), I can scan the network and add new
config found (if I know password or open network). And the new configuration
gets the connection immediately if 'ifup eth1' is not yet over.
If 'ifup eth1' is already finished:
========================================
...
...
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 14
DHCPDISCOVER on eth1 to 255.255.255.255 port 67 interval 5
No DHCPOFFERS received.
No working leases in persistent database - sleeping.
========================================
Just wake dhclient with 'dhclient eth1' to get the connection.
