If you can find software supporting any HDR bitmap formats to create the images, or have an HDR camera, you're most of the way there. The D3DTextureTool can load these into faces of a cubemap and save as DDS. ATI's CubeMapGen may also support HDR.

There is a photoshop plugin that lets you edit .dds files. Got some nice features on it as well with mipmaps etc.

Just google for it and you will find it.

Photoshop CS2 can edit HDR data. It doesn't have all of the filters that it has for 8 bit per channel data, but at least it gets the job done.

There are two separate DDS plug-ins for Photoshop; the NVIDIA plug-in (part of their Texture Tools) which is very feature rich, but may not support HDR (I haven't checked in a while); and the DirectX SDK DDS plug-in which explicitly supports HDR, but has less other features.

Note that you can get a 30 day free trial download of Photoshop from Adobe's web site, so you can use this for a while, if you don't already have PS. However, if you're going to be doing a lot of image editing, you owe it to yourself to find the money somewhere to buy it. If you're in school, there's probably educational discounts; if you work, just don't have any Starbucks for a few months :-)
