Quite easily if you don't mind a little side work. Here is what you can do.
1. Look up some piano music for gabriels Oboe (that's easy part)
2. Now most of the piano parts should have the melody note-for-note in the top treble hand
3. Take said melody and read it just as if you were reading B-flat Treble euphonium
4. If you don't read treble, then you can take the long route, download finale notepad, write in the melody line in the treble clef, and have it transpose it into a friendly bass clef.

Finding sheet music for solo Euphonium is rather difficult. If you read bass clef, it may be easier to simply find trombone sheet music and play off of that. If you read treble clef, go with trumpet sheet music. Both are Bb instruments like the Euphonium, and have similar tonal structure as well, so it wouldn't be too difficult to use those instead of Euphonium music. If that's not an option, websites such as sheetmusicplus.com, jwpepper.com, and musicnote.net can be a big help. Just search for common music publishers (Hal Leonard, for example) and see if they have online store fronts.
