gxt-support for openlayers/gwt-openlayers

[Mckeane]

Hello,
I am wondering if gxt supports openlayers or gwt-openlayers.
I want to display maps and some added functionality.
I currently have knowledge of gwt-openlayers for displaying maps using gwt and since gxt wraps around gwt or vice-versa that it automatically has support for gwt-openlayers.
If there is any other resource which can be used to display maps and has support for gxt, a link to that resource would be greatly appreciated.

Hello,
I wish to add openlayers overlay feature using gwt-openalyers wrapper to gxt tree panel. I have added the layers to the tree panel, however I am unable to select which layer should be visible based on the one selected from tree panel to support overlay or switch the layer completely.
I have please see images for screen shots:
This is what I've done so far:23998
This is what I hope to achieve * Java script was used*: 23999

I would also like to change the checkboxes to radio button or another button group so that more than one button cannot be checked.

TreePanel has no build in support for radios. You can listen to the CheckChange event of the TreePanel and decheck the other checked checkbox,
